The The invention relates to a method for producing a polymer layer composite from a plurality of substrate layers, in which at least a first, preferably personalizing and / or individualizing, information printing technology is stored, and such a polymer layer composite. As well The invention relates to a use of such a method or a polymer layer composite in the production of a safety and / or value document and / or a use of such a polymer layer composite as a security and / or value document.

State of the art and background the invention

modern Security and / or value documents are or are as a polymer layer composite formed or made of such or include one such. Security and / or value documents usually include personalizing and / or individualizing information that an assignment of the security and / or value document to a Person and / or a group of persons, objects and / or Allows entities.

A individualizing information is, for example, a serial number or an indication of the issuing authority. The personalizing and / or individualizing information about it A security feature is a security feature Feature of a security and / or value document, which is a copy and / or forgery and / or copying of the value and / or security document prevent or at least complicate.

When Personalizing information is considered to be one of Include person-assignable information. This can For example, image information, such as a passport photo, a Fingerprint, etc., or alphanumeric strings, such as a Name, address, place of residence, date of birth, etc.

When Security and / or value documents are merely exemplary called: identity cards, passports, ID cards, access control cards, Visas, tax stamps, tickets, driving licenses, motor vehicle papers, Bank cards, credit cards, banknotes, checks, postage stamps, credit cards, Any chip cards and adhesive labels (eg for product protection).

From the prior art, different methods for the production of value and / or security documents are known. For example, in the publications US 6,022,429 . US 6,264,296 . US 6,685,312 . US 6,932,527 . US 6,979,141 and US 7,037,013 Such methods are described in which an inkjet print is applied to finished blanks, which is to be protected with a protective lacquer or a protective film as protection against mechanical and / or chemical damage and manipulation. With this method, personalizing and / or individualizing information can be stored in color in the security and / or value document by printing technology. However, the resulting security and / or value documents have only a relatively small security against manipulation, because the printed information is completely printed relatively near the surface and the protective layer of paint or a protective film usually no monolithic, cohesive connection with the card blank forms and thus removable and / or removable. Subsequent manipulation of the printed matter is possible.

The pamphlets US 7,005,003 B2 . EP 0 131 145 B1 . US 5,734,800 and US 6,765,693 B1 describe methods for printing color images with different color separations.

From the EP 1 322 480 B1 a recording medium, in particular a credit or identity card, having an upper layer and further layers is known, wherein the upper layer has on its outer side a plurality of lenticular lenses and on the back a display element, which appears to be movable when tilting the recording medium about at least one axis, and The lenticular lenses extend over only a partial area of the entire outer side and the display element is a security element which is printed on an inner card layer. The upper layer with the lenticular lenses arranged thereon and the remaining layers of the recording medium are made of polycarbonate. As security element a security guilloche is described.

Also from the WO 01/29764 A1 is a card-shaped disk with authenticity elements in the interior known, which consists of at least one cover sheet and arranged on the top optical readout system, through which the arranged inside the fastness elements from mindes at least two different viewing directions are readable with different information content, wherein the optical readout system consists of a lens structure of Fresnel lenses.

Technical problem of the invention

Of the Invention is the technical problem underlying a method for Producing a polymer layer composite and such a polymer layer composite to create, in the at least one first information by printing is or will be part of a security feature which is a viewing angle dependent color effect so that the first information is opposite one Manipulation and / or falsification and / or such Polymer composite are better protected against imitation than in the polymer layer composite systems known from the prior art, and thus in particular as a value and / or security document or as part of a value and / or security document or as part of a manufacturing process of such value and / or Security document can be used.

Broad features of the invention and preferred embodiments

To solve the problem, a method for producing a polymer layer composite from a plurality of substrate layers, in which at least one first information is stored by printing technology, has been proposed, which comprises the steps of providing a plurality of polymer layers as the substrate layers, printing the first information on at least one substrate layer, gathering the substrate layers to form a substrate layer stack and laminating the substrate layers to a polymer layer composite, it being provided according to the invention that the first information is decomposed into at least two pressure extracts, each comprising a partial information of the first information and the printing of the first information in which the at least two Druckauszüge be printed on at least two different substrate layer surfaces matched, so that the printed pressure separations in the polymer layer composite are exactly one above the other and together the first e reproduce information at a viewing angle and at least one color change of the reproduced first information occurs under at least one second viewing angle. The invention thus provides a polymer layer composite which is produced by lamination of a plurality of substrate layers and in which at least one first information is stored by printing technology, wherein the substrate layers are polymer layers and wherein the first information is decomposed into at least two pressure separations, each comprising a partial information of the first information and the at least two printing separations are printed in at least two spaced-apart planes or the at least two printed printing separations are arranged in at least two spaced-apart planes such that the printed printing separations in the polymer layer composite lie one above the other in register and collectively the first information at a viewing angle reproduce and at least a color change of the reproduced first information occurs under at least a second viewing angle. The resulting polymer layer composite thus comprises, incorporated in a composite body, first information stored in at least two spaced apart planes so as to collectively represent the first information at a viewing angle. At least one second, different viewing angle results in at least one color change. This means that a spectral distribution of the observable light is different for the two different viewing angles. However, it may also be a change in the reproduced first information set. For example, a portion of the first information may be obscured and, for this purpose, a second information stored in substrate layers or substrate substrate surfaces underlying it in the document body may be visible. Compared to the application of a first information in the interior of a polymer layer composite according to the prior art, an increased Fäl security, since at least two levels of information must be manipulated. Further, a security feature is created by printing technology, which is easy to verify, but is not duplicated by a copy operation. In particular, first information comprising a high-resolution pattern or image is difficult to imitate because of high precision in aligning the print separations with each other to correctly reproduce the first information. Preferably, the first information is personalizing and / or individualizing information. The created security feature can thus be used to store personalizing and / or individualizing information in the polymer layer composite in such a way that it is easily possible to verify the authenticity of the information about the resulting color change under the at least two different viewing angles.

The first information is multicolored, preferably colorful. This means that the first information is not one Reproduce printing ink. As multicolor becomes one Information viewed if there are at least two color impressions in a viewer causes brightness differences here should not represent different color impressions. As colorful information is considered more than three different Color impressions causes, of which preferably at least a color impression by additive color mixing (with luminescent Colors) or subtractive color mixing (in so-called body colors) from primary colors that span a color space or can be caused. Particularly preferably, the first information a colorful or multicolored personalizing Face picture of a person.

at an embodiment is provided that a through the first information embodied print image in pixels is decomposed and each pixel exactly one of the at least two Is assigned to print separations. The assignment is thus made so that each pixel is assigned exactly to a printout. In embodiments where more than the at least Two snaps are used this means that each pixel is assigned to exactly one of the several print separations becomes. When arranging the pressure separations one above the other in a substrate layer stack to which the substrate layers are gathered be before joining to the document body is thus, along a lamination direction (or opposite the lamination direction) above one on a substrate layer applied pixel in any other arranged above the substrate layers or substrate layer surfaces Pixel or part of the pixel of the first information arranged. A pixel in the sense used here has exactly a color that matches an ink or ink. Furthermore, each pixel is a position in a generated two-dimensional Print image assigned to the first information.

at another embodiment may be provided that individual or all of the indentations are multiple, but accurate on different, preferably in the composite body spaced, Substrate layer surfaces are printed, for example to get a better opacity.

As well it is provided in one embodiment, the pixels to assign several print separations during disassembly, However, in such a way that in the composite body only the same Pixel is arranged in different levels. A pixel has only one ink in all printouts here.

at an embodiment, it is provided that the pressure separations in terms of their spacing in the polymer layer composite of a upper viewing page (front) are sorted hierarchically, wherein the most distant from the viewing side pressure separation a lowest hierarchy level is assigned and the print separations be modified by adding pixels of the printing extracts, which no pixel is assigned, the corresponding pixel, however assigned to a printout of a higher hierarchical level is, a pixel is assigned to a second information. The Prints are thus pixels in those places the second information assigned by a pixel of the first information on an overlying substrate layer surface of the substrate layer stack or an overlying one Covered level of the composite body in a vertical plan view are. This provides more than in embodiments Use two indentations on at least three different ones spaced substrate layer surfaces are printed, the advantage that at lower levels, d. H. hierarchically lower levels, a number of the printed pixels of the first information, the by printed pixels of a printout of a hierarchically higher Level at a viewing, from a vertical top view deviates, becomes obscured, or whose occlusion becomes more opaque or opaque fails, increases.

The second information can be formed here as desired. In one embodiment, the pixels of the second information all have a uniform color. These images are or will be preferred dots of the second information white or black opaque or cover printed.

at In other embodiments, the second information may be colored be and be derived from the first information or complete be given independently. For example, one is Embodiment provided that the second information depending on the pixels of the first information in Derived from the individual pressure extracts. Own one Pixels of a printout, which in plan view through it arranged pixel of the first information is hidden, a adjacent pixel, which is a pixel of the first information represents, so this one color, depending on associated with the color of the adjacent pixel of the first information be, so that the most pronounced color effect a tilting of the substrate layer composite, d. H. at a change the viewing direction occurs.

Especially reliable color change effects can be achieve, if at least with respect to a selected Direction, preferably with respect to two mutually orthogonal Directions, adjacent pixels each different pressure extracts be assigned. Immediately adjacent pixels along the Excellent direction are thus always different pressure extracts assigned. Preferably, there are also along a second to the excellent direction orthogonal direction none immediate neighboring pixels of the first information, the same printout are assigned. The pixels become, for example, alternating along the excellent direction the two print outs assigned.

One additional auszuschutzender as another security feature Effect is realized with an embodiment in which on a substrate layer surface or in one of the substrate layers at least in the area where the first information is presented Luminescent agent is introduced in such a way that at an UV excitation a surface white radiation Light takes place and the substrate layer surface or substrate layer below at least one, preferably all, of the at least two Pressure extracts in the produced document body is arranged. UV radiation turns the white fluorescence stimulated. This includes light of different wavelengths, the color addition a white color impression causes. The light is now in through the pixels of it above arranged or printed pressure separations filtered, so that again the first information under a viewing angle, preferably in a vertical plan view, can be seen in color. If the security document is tilted, it overlaps at least those printed in neighboring different levels Pixels of the first information along a line of sight or a light propagation direction of the fluorescent light to an eye a viewer or a detection device. It takes place a double filter, which is usually a shade change or at least a change in the brightness of a hue causes. Additionally you can on pixels of the second See information under pixels of the first information. This also performs if the second information exists is, to a change in information perception.

A independently inventive embodiment of a Polymer layer composite with a viewing angle dependent Security feature is obtained by looking at the first information, which is preferably individualizing and / or personalizing, printing on a substrate layer surface and on a substrate layer surface underlying it in the polymer layer composite or a substrate layer underlying it in the polymer layer composite Luminescent on or brings. A multilayer print of the first information is not required.

at In some embodiments, it is advantageous if the printed pixels of at least one of the at least two printing extracts partially transparent in at least one wavelength range or translucent. This can be achieved by at least one of the at least two indentations with a translucent or semi-transparent ink or ink prints. An ink is translucent or semi-transparent when printed in the printed condition in the finished document body translucent or semi-transparent is.

Farther It is possible, instead of a white luminescence to use a luminescence that emits in one color. These would be completely absorbed by some colors, by others However, transmits, so hereby an angle-dependent Luminescence can be generated. It is also possible different luminescent colors to use and beside, over, or to place them together to combine the effects. one above the other means a vertical distance in different substrate layers, Together they are a real mixture that has a white luminescence or occupy another part of the spectrum. The emission of wavelengths outside the visible Spectral range is explicitly included.

Furthermore, it is possible to use at least one of the at least two print separations with fluorescent dye ben or inks that emit light in the visible wavelength range only after excitation with UV light. As a result, a viewing-angle-dependent "hidden" first information can be introduced into the security document in a simple manner.

Around to increase counterfeiting and / or manipulation security, become the substrate layers in one embodiment so gathered that with the at least two pressure separations printed substrate layer surfaces inside surfaces in the substrate layer stack.

at In a preferred embodiment, the at least two print separations a monochrome color separation of an n-color color system, in particular a tri-color system, or an n-color black system, especially a three-color black color system. Offer this All known n-color color systems, with which colorful or multicolored information can be displayed, with the colorful information More color values include used as printing inks for making become. With a three-color color system, for example with the Colors yellow, magenta, cyan, can be a lot of human perceptible color space by exploiting the color subtraction create in the human perception of colors. Likewise However, color systems that use more than three colors are also used or more than three colors and black, for example, six colors plus black.

at an embodiment of the invention include the at least two separations m monochrome separations, the each printed on different substrate layer surfaces become. Here m is an integer, usually with a Number n will match the number of colors of the indicates the color system used. However, it is also conceivable that the first personalizing and / or individualizing information into a larger number of monochrome printouts is decomposed so that for single or all colors of the Color system two monochrome print outs exist, the in each case a partial information of the first personalizing and / or include individualizing information. This several monochrome Prints for a color can of course different partial information of the first personalizing and / or individualizing information.

A precise alignment of the at least two pressure separations is particularly easy to implement in one embodiment, at the two or at least two pressure separations on opposite surfaces of the same substrate layer printed with register accuracy, the printed separations to each other when viewing the surfaces are mirrored. This means that the one printout that is on top of the Substrate layer is printed, the top of the substrate stack from which the individualizing and / or personalizing first information should be perceptible, not mirrored imprinted is. On an underside of the same substrate layer is then the Printout mirror printed on the substrate layer now viewed from the bottom. Seen from the top complement the at least two pressure separations correct to the personalizing and / or individualizing first information.

Around the first personalizing and / or individualizing information to be able to perceive correctly, it is understood that the Substrate layers between the individual pressure separations and above, transparent or, if they are are not transparent, are at least translucent. Preferably, all of these substrate layers are transparent.

is the substrate layer or is at least one of the substrate layers between the at least two substrate layer surfaces on which the at least two snapshots, one each Partial information of the first, preferably individualizing and / or personalizing, information include, imprinted, translucent, so it is particularly preferred if the entire polymer layer composite, at least in the area where the first, preferably individualizing and / or personalizing, information is stored, translucent, d. H. not opaque, is. This way you can preferably personalized and / or individualized, Durchsichtpasser generate the total information when viewed in backlight represents. It is thus provided in one embodiment that the polymer layers all, at least in one area, in the one of the substrate layer surfaces with one of the pressure separations is printed, or at least in an area where one of the in the polymer layer composite arranged above or below Substrate layers is printed with one of the printing extracts or, transparent and / or translucent polymer layers are provided wherein at least one, preferably exactly one, polymer layer, which is arranged between two of the at least two pressure separations is provided as a translucent polymer layer. The remaining Polymer layers are preferably all transparent.

at In another embodiment it is provided that at least two of the at least two print separations on substrate layer surfaces different substrate layers are printed.

Around For example, a reflection of one or more pressure extracts to avoid how this is necessary when undersides of the one above the other arranged substrate layers are printed, it is at a Embodiment preferred that all of the at least two Pressure extracts on substrate layer surfaces different Substrates are printed.

Around to achieve that the different printed separations also in the produced polymer layer composite in different Layers are arranged, in one embodiment of the Invention provided that the plurality of substrate layers so collected be that the substrate layer surfaces that with a the at least two indentations are printed in the Substrate stacks are not directly adjacent to each other.

Become the at least two indentations do not differ on Substrate layer surfaces of the same substrate layer printed, the substrate layers are preferably gathering aligned with each other so that the at least two pressure separations in register in the substrate layer stack exactly on top of each other are arranged. This assumes that the substrate layers are formed essentially of the same polymer or at least the same expansion and / or shrinkage properties of cohesive Connecting the individual substrate layers have during lamination.

In principle, all materials customary in the field of security and / or value documents can be used as materials for the polymer layers. The polymer layers can, identically or differently, be based on a polymer material from the group comprising PC (polycarbonate, especially bisphenol A polycarbonate), PET (polyethylene glycol terephthalate), PMMA (polymethyl methacrylate), TPU (thermoplastic polyurethane elastomers), PE (polyethylene), PP ( Polypropylene), PI (polyimide or poly-trans-isoprene), ABS (acrylonitrile-butadiene-styrene), PVC (polyvinyl chloride) and copolymers of such polymers. Preference is given to the use of PC materials, whereby, for example, but by no means necessarily, so-called low-T _g materials are used, in particular for the polymer layers on which the print separations are printed, and / or for the polymer layers, which with the or the polymer layers that are printed on the side with the inkjet printing. Low-T _g materials are polymers whose glass transition temperature is below 140 ° C.

The Polymer layers can be filled or unfilled be used. Contain the filled polymer layers in particular colorants, which include both dyes and color pigments or other fillers. The polymer layers can also be dyed by means of dyes or colorless and in the latter case transparent or translucent.

It is preferred if the base polymer of at least one of the polymer layers to be joined contains identical or different mutually reactive groups, wherein react at a laminating temperature of less than 200 ° C reactive groups of a first polymer layer with each other and / or with reactive groups of a second polymer layer. As a result, the lamination temperature can be lowered without jeopardizing the intimate bond of the laminated layers. In the case of various polymer layers having reactive groups, this is due to the fact that the various polymer layers can no longer be readily delaminated due to the reaction of the respective reactive groups with one another and the formation of covalent chemical bonds. Because there is a reactive coupling between the polymer layers, as it were a reactive lamination. Furthermore, because of the lower laminating temperature, it is possible to prevent a change in the colored printing ink, in particular a color change. It is preferred in this case if the glass transition temperature T _{g of} the at least one polymer layer before thermal lamination is less than 140 ° C. (or less than 120 ° C. or less than 100 ° C.), the glass transition temperature of this polymer layer after thermal lamination Reaction of reactive groups of the base polymer of the polymer layer with each other by at least 5 ° C, preferably at least 20 ° C, higher than the glass transition temperature before the thermal lamination. In this case, not only is a reactive coupling of the layers to be laminated together carried out, but rather an increase in the molecular weight and thus in the glass transition temperature takes place by crosslinking of the polymer within the layer and between the layers. This complicates delamination, splitting, in addition, especially as in a manipulation attempt, the high delamination temperatures necessary z. B. can irreversibly damage the colors and so the document is destroyed. Preferably, the lamination temperature when using such polymer materials less than 180 ° C, more preferably still less than 150 ° C. The choice of suitable reactive groups is readily possible for a person skilled in the art of polymer chemistry. at play exemplary reactive groups are selected from the group consisting of -CN, -OCN, -NCO, -NC, -SH, -S _x, -Tos, -SCN, -NCS, -H, epoxy (-CHOCH _2), -NH ₂ , -NN ⁺ , -NN-R, -OH, -COOH, -CHO, -COOR, -Hal (-F, -Cl, -Br, -I), -Me-Hal (Me = at least divalent metal, for example Mg), -Si (OR) ₃ , -SiHal ₃ , -CH = CH ₂ , and -COR, where R can be any reactive or non-reactive group, for example -H, -Hal, C ₁ -C ₂₀ - Alkyl, C ₃ -C ₂₀ aryl, C ₄ -C ₂₀ -ArAlkyl, each branched or linear, saturated or unsaturated, optionally substituted, or corresponding heterocycles having one or more identical or different heteroatoms N, O, or S. Other reactive Of course, groups are possible. These include the reaction partners of the Diels-Alder reaction or a metathesis. The reactive groups may be attached directly to the base polymer or linked to the base polymer via a spacer group. Suitable spacer groups are all spacer groups known to the person skilled in the art of polymer chemistry. The spacer groups may also be oligomers or polymers which impart elasticity, whereby a risk of breakage of the security and / or value document is reduced. Such elasticity-promoting spacer groups are known to the person skilled in the art and therefore need not be further described here. By way of example only, spacer groups may be mentioned which are selected from the group comprising - (CH ₂ ) _n , - (CH ₂ -CH ₂ -O) _n -, - (SiR ₂ -O) _n -, - (C ₆ H ₄ ) _n -, - (C ₆ H ₁₀ ) _n , C ₁ -C _n -alkyl, C ₃ -C _{(n + 3)} -aryl, C ₄ -C _{(n + 4)} -ArAlkyl, each branched or linear, saturated or unsaturated, optionally substituted, or corresponding heterocycles having one or more, identical or different heteroatoms O, N, or S, where n = 1 to 20, preferably 1 to 10. Regarding further reactive groups or possibilities of modification is to the reference "Ullmann's Encyclopedia of Industrial Chemistry", Wiley Verlag, electronic edition 2006 , referenced. The term "base polymer" in the context of the above statements designates a polymer structure which does not bear any groups reactive under the lamination conditions used. These may be homopolymers or copolymers. There are also modified polymers compared to said polymers.

Advantageous it is when at least partially polycarbonate as polymer layers (PC) layers are provided, preferably only PC layers. Polymer layer composite systems, the personalizing and / or individualizing Information includes, in particular monolithic polymer layer composite systems, that consists of polymer layers of a plastic material (of a polymer) can or are produced very well as safety and / or value documents are used. A preferred embodiment provides, therefore, that the polymer layer composite as a security document or value document is formed.

at an embodiment is therefore provided that further, pertinent known security elements and / or security features applied to and / or in the substrate layers and / or introduced. Of course, security elements can and / or security features also between the substrate layers in the substrate layer stack are introduced before lamination. Likewise, an application or introduction into the finished laminated polymer layers composite, For example, about laser engraving, etc., possible.

Further it is possible that in addition in the polymer layer stack one or more non-polymeric materials prior to lamination in particular paper, existing further substrate layers inserted Be that, or are, that they are after lamination no longer destructive of adjacent substrate layers and / or other adjacent substrate layers dissolved can or can. To paper layers in a polymer layer composite it is, for example, to be able to embed in the manner indicated advantageous, the further paper-based substrate layer with openings and / or recesses through which during lamination adjacent to the paper base formed further substrate layer polymeriche substrate layers through each other a compound can train.

When further security elements and / or security features are exemplary introduced diffractive structures, holograms, imprints, a provision of special printing elements such as guilloche or iris printing etc. use of certain colors an introduction of laser engraving etc. mentioned. It results for the skilled person that all known in the art security features in addition can be used.

As a further security element, one or more electronic circuits and / or a microchip can be introduced into the polymer layer composite. The electronic circuit may in this case be a discrete component such as an inductor, a capacitor, an electrical resistor, a diode, a transistor, a memory element, a display element or a combination of a plurality of these components comprising an oscillator, an amplifier , a microcontroller or a display. A structure as an integrated circuit proves to be advantageous. This electronic circuit gene and / or microchips are often designed so that they can be read out and / or described without contact. In order to prevent and / or protect a replacement or manipulation of one of the electronic circuits and / or the microchip, one embodiment provides one or more electronic circuits and / or a first surface of a substrate layer designated as an inlay layer or one or more recesses of the inlay layer apply or apply a microchip and then print one of the at least two print separations on this first surface. Each replacement and / or removal of the microchip and / or the one or more electronic circuits causes in such a case also a change in the first personalizing and / or individualizing information and thus is easy to perceive for a viewer.

A Another embodiment provides that a transparent or translucent diffractive security element at least partially When printing one of the print separations is printed directly. A further development provides that the diffractive security element, for example, a hologram, applied to a substrate layer which is already printed with one of the print separations and then with another of the pressure separations at least partially directly overprinted. Furthermore is It is of course possible, the diffractive element apply to a substrate layer before the first printing step, and to print this afterwards. Furthermore it can work on a already existing pressure extractor are applied and then with a printing of a substrate layer surface disposed thereover be brought into contact surface, so that the diffractive Element is covered on both sides by pressure separations, d. H. adjacent to these printed impressions in the polymer layer composite is introduced. The introduction of a diffractive element can thus before and / or after and / or between the printing of one or more of the substrate layer surfaces take place. The diffractive Security element is thus optimally against replacement in the frame protected against manipulation of a security document.

additionally for a verification of the viewing direction-dependent security feature by looking from different directions can also a verification with aids are carried out. A separate lens or lenticular can be used as a verification instrument, just hang up. By slightly shifting this lens raster Thus deeper levels are visible. Leave by tilting the document itself with appropriate screening of the printed information produce different color impressions or shifts.

The Applying the first personalized information can be easy or in multiple use, especially in dual use, in roles provided polymer layers or provided in sheets Polymer layers take place. An orientation of the individual substrate layers can be monitored by optical control methods. Likewise, a use of mechanical investment marks, in particular in a gathering of the substrate layers in the form of substrate sheets, used.

at An embodiment of the invention provides that printed on the multiple substrate layers a plurality of first information be and from the polymer composite several security and / or Value documents, preferably by cutting them out or punched out.

One Printing the substrate layer surfaces with the different ones Prints are made by digital printing. In particular, the at least two pressure extracts by means of a transfer printing method or a sublimation printing method or a diffusion transfer process or a re-transfer process or more preferably, an ink-jet printing method (inkjet printing method) and / or a combination of these printed.

The high molecular weight polycarbonate derivatives from the diphenols of the formula (Ia), optionally in combination with other diphenols, can be prepared by the known polycarbonate production processes. The various diphenols can be linked together both statistically and in blocks. The polycarbonate derivatives used can be branched in a manner known per se. If the branching is desired, this can in known manner by condensing small amounts, preferably amounts of 0.05 to 2.0 mol% (based on diphenols), of trifunctional or more than trifunctional compounds, in particular those with three or more than three phenolic hydroxyl groups can be achieved. Some branching agents having three or more than three phenolic hydroxyl groups are: phloroglucinol, 4,6-dimethyl-2,4,6-tri- (4-hydroxyphenyl) -hegten-2,4,6-dimethyl-2,4,6- tri- (4-hydroxyphenyl) heptane, 1,3,5-tri- (4-hydroxyphenyl) -benzene, 1,1,1-tri- (4-hydroxyphenyl) -ethane, tri- (4-hydroxyphenyl) - phenylmethane, 2,2-bis [4,4-bis (4-hydroxyphenyl) cyclohexyl] -propane, 2,4-bis (4-hydroxyphenyl-isopropyl) -phenol, 2,6-is- (2 -hydroxy-5-methyl-benzyl) -4-methylphenol, 2- (4-hydroxyphenyl) -2- (2,4-dihydroxyphenyl) -propane, hexa- [4- (4-hydroxyphenyl-isopropyl) -phenyl] - orthoterephthalic acid ester, tetra (4-hydroxyphenyl) methane, tetra- [4- (4-hydroxyphenyl-isopropyl) -phenoxy] -methane and 1,4-bis- [4 ', 4 "-dihydroxytriphenyl) -methyl] -benzene , Some of the other trifunctional compounds are 2,4-dihydroxybenzoic acid, trimesic acid, cyanuric chloride and 3,3-bis (3-methyl-4-hydroxyphenyl) -2-oxo-2,3-dihydroindole. As chain terminators known per se regulation of the molecular weight of the polycarbonate derivatives are monofunctional compounds in conventional concentrates. Suitable compounds are for. As phenol, tert-butylphenols or other alkyl-substituted phenols. For controlling the molecular weight, in particular small amounts of phenols of the formula (Ic) are suitable

wherein R represents a branched C ₈ and / or C ₉ alkyl radical. Preferably, in the alkyl radical R, the proportion of CH ₃ protons between 47% and 89% and the proportion of CH and CH ₂ protons between 53% and 11%; also preferably R is in the o- and / or p-position to the OH group, and more preferably the upper limit of the ortho-portion is 20%. The chain terminators are generally used in amounts of 0.5 to 10, preferably 1.5 to 8 mol%, based on diphenols used. The polycarbonate derivatives may preferably be prepared according to the interfacial behavior (cf. H. Schnell "Chemistry and Physics of Polycarbonates", Polymer Reviews, Vol. IX, p. 33ff., Interscience Publ. 1964 ) are prepared in a conventional manner. In this case, the diphenols of the formula (Ia) are dissolved in an aqueous alkaline phase. For the preparation of copolycarbonates with other diphenols, mixtures of diphenols of the formula (Ia) and the other diphenols, for example those of the formula (Ib), are used. To regulate the molecular weight chain terminators z. B. the formula (Ic) are added. Then, in the presence of an inert, preferably polycarbonate-dissolving, organic phase is reacted with phosgene by the method of interfacial condensation. The reaction temperature is between 0 ° C and 40 ° C. The optionally used branching agents (preferably from 0.05 to 2.0 mol%) can either be initially charged with the diphenols in the aqueous alkaline phase or dissolved in the organic solvent prior to phosgenation the. In addition to the diphenols of the formula (Ia) and, if appropriate, other diphenols (Ib), their mono- and / or bis-chlorocarbonic acid esters may also be used, these being added dissolved in organic solvents. The amount of chain terminators and of branching agents then depends on the molar amount of diphenolate radicals corresponding to formula (Ia) and optionally formula (Ib); When using chloroformates the amount of phosgene can be reduced accordingly in a known manner. Suitable organic solvents for the chain terminators and optionally for the branching agents and the chloroformates are, for example, methylene chloride, chlorobenzene and in particular mixtures of methylene chloride and chlorobenzene. Optionally, the chain terminators and branching agents used can be dissolved in the same solvent. For example, methylene chloride, chlorobenzene and mixtures of methylene chloride and chlorobenzene serve as the organic phase for the interfacial polycondensation. The aqueous alkaline phase used is, for example, NaOH solution. The preparation of the polycarbonate derivatives by the interfacial process can be catalyzed in a conventional manner by catalysts such as tertiary amines, in particular tertiary aliphatic amines such as tributylamine or triethylamine; the catalysts can be used in amounts of 0.05 to 10 mol%, based on moles of diphenols used. The catalysts can be added before the beginning of the phosgenation or during or after the phosgenation. The polycarbonate derivatives can be prepared by the known method in the homogeneous phase, the so-called "pyridine process" and by the known melt transesterification process using, for example, diphenyl carbonate instead of phosgene. The polycarbonate derivatives may be linear or branched, they are homopolycarbonates or copolycarbonates based on the diphenols of the formula (Ia).

The organic solvents used are preferably halogen-free organic solvents. In particular, aliphatic, cycloaliphatic, aromatic Hydrocarbons, such as mesitylene, 1,2,4-trimethylbenzene, cumene and solvent naphtha, toluene, xylene; (organic) esters, such as methyl acetate, Ethyl acetate, butyl acetate, methoxypropyl acetate, ethyl 3-ethoxypropionate.

The Preparation may contain in detail: A) 0.1 to 10 wt .-%, in particular 0.5 to 5 wt .-%, of a binder with a polycarbonate derivative based on a geminally disubstituted dihydroxydiphenylcycloalkane, B) 40 to 99.9 wt .-%, in particular 45 to 99.5 wt .-%, of an organic Solvent or solvent mixture, C) 0.1 to 6 wt .-%, in particular 0.5 to 4 wt .-%, of a colorant or colorant mixture, D) 0.001 to 6 wt .-%, in particular 0.1 to 4% by weight of a functional material or mixture of functional Materials, E) 0.1 to 30% by weight, in particular 1 to 20% by weight, Additives and / or auxiliaries, or a mixture of such substances.

As component C, if a colorant is to be provided, basically any colorant or colorant mixture comes into question. Colorants are all colorants. That means it can be both colorant (a review of dyes there Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2007, Wiley Publishing, Chapter "Dyes, General Survey" ) as well as pigments (gives an overview of organic and inorganic pigments Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2007, Wiley Verlag, chapter "Pigments, Organic" and "Pigments, Inorganic" ) act. Dyes should be soluble or (stably) dispersible or suspendible in the component B solvents. Furthermore, it is advantageous if the colorant at temperatures of 160 ° C and more for a period of more than 5 min. stable, in particular color-stable. It is also possible that the colorant is subjected to a predetermined and reproducible color change under the processing conditions and is selected accordingly. In addition to the temperature stability, pigments must be present in particular in the finest particle size distribution. In the practice of inkjet printing, this means that the particle size should not exceed 1.0 microns, otherwise blockages in the printhead will result. As a rule, nanoscale solid-state pigments and dissolved dyes have proven their worth. The colorants may be cationic, anionic or even neutral. Just as examples of colorants usable in ink-jet printing its called:
Brilliant black CI no. 28440, chromogen CI no. 14645, direct Tiefschwarz E CI no. 30235, Real Black Salt B CI no. 37245, Real Black Salt K CI no. 37190, Sudan Black HB CI 26150, Naphtolschwarz CI no. 20470, Bayscript ^® Black liquid, CI Basic Black 11, CI Basic Blue 154, Cartasol ^® Turquoise K-ZL liquid, Cartasol ^® Turquoise K-RL liquid (CI Basic Blue 140), Cartasol Blue K5R liquid.

Furthermore, as soluble colorants anthraquinone, azo, quinophthalone, coumarin, methine, perinone, and / or pyrazole, z. B. under the brand name Macrolex ^® available, find use. Other suitable colorants are in the reference Ullmann's Encyclopedia of Industrial Chemistry, Electronic Release 2007, Wiley Verlag, chapter "Colorants Used in Ink Jet Inks" described. Well-soluble colorants lead to an optimal integration into the matrix or the binder of the print layer. The colorants may be added either directly as a dye or pigment or as a paste, a mixture of dye and pigment together with another binder. This additional binder should be chemically compatible with the other components of the formulation. If such a paste is used as a colorant, the amount of component B refers to the colorant without the other components of the paste. These other components of the paste are then subsumed under the component E. When using so-called colored pigments in the scale colors cyan-magenta-yellow and preferably also (soot) black solid color images are possible.

Component D comprises substances that can be seen directly by the human eye or by the use of suitable detectors using technical aids.

These include luminescent substances (dyes or pigments, organic or inorganic) such. As photoluminophores, electroluminophores, Antistokes luminophores, fluorophores but also magnetizable, photoacoustically addressable or piezoelectric materials. Furthermore, Raman-active or Raman-enhancing materials can be used, as well as so-called barcode materials. Again, the preferred criteria are either the solubility in the component B or pigmented systems particle sizes <1 micron and a temperature stability for temperatures> 160 ° C in the sense of the comments on the component C. Functional materials can be added directly or via a paste, ie a mixture with a further binder, which then forms part of component E, or the binder of component A.

Component E in inks for ink-jet printing includes conventionally prepared materials such as anti-foaming agents, modifiers, wetting agents, surfactants, flow agents, dryers, catalysts, (light) stabilizers, preservatives, biocides, surfactants, organic polymers for viscosity adjustment, buffer systems, etc. As setting agents customary setting salts come into question. An example of this is sodium lactate. As biocides, all commercially available preservatives which are used for inks come into question. Examples include Proxel ^® GXL and Parmetol® ^® A26. Suitable surfactants are all commercially available surfactants which are used for inks. Preferred are amphoteric or nonionic surfactants. Of course, it is also the use of special anionic or cationic surfactants which the properties of the color Do not change fabric, possible. Examples of suitable surfactants are betaines, ethoxylated diols, etc. Examples are the product lines Surfynol ^® and Tergitol ^®. The amount of surfactants is particularly selected in an application for ink-jet printing, for example, with the proviso that the surface tension of the ink is in the range of 10 to 60 mN / m, preferably 20 to 45 mN / m, measured at 25 ° C. A buffer system can be set up which stabilizes the pH in the range from 2.5 to 8.5, in particular in the range from 5 to 8. Suitable buffer systems are lithium acetate, borate buffer, triethanolamine or acetic acid / sodium acetate. A buffer system will be considered in particular in the case of a substantially aqueous component B. To adjust the viscosity of the ink (possibly water-soluble) polymers can be provided.

An example of the latter block copolymer is the product series Pluronic ^®. The proportion of biocide, based on the total amount of ink, may be in the range of 0 to 0.5% by weight, preferably 0.1 to 0.3% by weight. The proportion of surfactant, based on the total amount of ink, can range from 0 to 0.2 wt .-%. The proportion of adjusting agents, based on the total amount of ink, 0 to 1 wt .-%, preferably 0.1 to 0.5 wt .-%, amount. The auxiliaries also include other components, such as, for example, acetic acid, formic acid or n-methyl-pyrrolidone or other polymers from the dye solution or paste used.

To produce a polymer layer composite, at least three polymer layers are required as substrate layers if a first information to be introduced is to be protected against manipulation in the interior of the polymer layer composite to be produced. The polymer films are on the rollers 2 - 4 arranged. Optionally, one or more further, in particular one to twelve, more preferably two to ten and particularly preferably four to six, polymer layers may be supplied on rollers. These possible additional polymer layers provided as substrate are via the roll 5 , which is shown in dashed lines, symbolizes. The one of the roles 2 - 5 provided or supplied polymer layers 6 - 9 have thicknesses between 5 μm and 350 μm, preferably between 50 μm and 150 μm. The individual polymer layers 6 - 9 can all have the same strength or different strengths.

A preferably designed as a computer control unit 10 a first information, for example in the form of a computer data set, is supplied. The first information is preferably personalizing and / or individualizing information and may include, for example, a colored face image (passport photograph) as well as personal information such as last name, first name, date of birth, place of residence, place of birth, street, house number, postal code, etc. The control unit 10 is designed so that it decomposes the first information into at least two printing extracts, each comprising a partial information of the first information. For example, three monochrome color separations in a cyan-magenta-yellow color space or color system are produced by the colored face image. In addition, a fourth color separation for black and / or gray image components can be created. The at least two color print separations, which are identical, for example, to the monochrome color separations or represent a combination of two monochrome color separations, are printed units 11-14 transmitted. Likewise, the first information may be decomposed into printing extracts, each of which is multi-colored, that is, comprising pixels to be printed with inks and / or inks having a different color. These printing units 11 - 14 are designed as digital printing units, which means that they perform a digital printing process. Preferably, the printing units 11 - 14 designed as inkjet printing units. In some embodiments, the various printing units 11 - 14 also print by various digital printing methods. Ink jet printing units are particularly well suited for printing multicolor print separations, so that the individual pixels of a print separation, which have different colors within the print separation, exactly their predetermined distances and positions.

In one embodiment, only the three polymer layers 6 - 8th from the roles 2 - 4 be made available via the printing units 11 and 12 for example, two printing extracts on opposite surfaces of the polymer layer 7 printed in perfect register. This means that on the substrate layer passing through the polymer layer 7 is provided on a top 15 ie an upper substrate layer surface, by the printing unit 11 , For example, a printout is printed, which comprises one half of the alternately assigned pixels of the first information. On a bottom 16 (a lower substrate layer surface) through the polymer layer 7 provided substrate layer is through the printing unit 12 imprinted in register with the first printout the second printout, which comprises a different half of the alternately assigned pixels of the first information.

In other embodiments, the printing units 11 - 14 each print a monochromatic color separation of a three-color black color system, the black color separation is also considered here as a monochromatic color expression. This means that the printing units 13 and 14 on the polymer layer 9 print exactly the same two different print separations. In such a case, it is advantageous if between the polymer layers 7 and 9 a further transparent polymer layer is inserted (not shown), so that the of the printing units 12 and 13 printed pressure separations in the finished polymer layer composite are spaced from each other. However, this is not mandatory. In other embodiments, printing of the inner substrate layer surfaces of the outer substrate layers (polymer layers) may also be provided.

The polymer layers 6 - 8th respectively. 6 - 9 be over pulleys 17 guided and to a polymer layer stack or substrate layer stack 18 merged. The gathering or merging of the individual polymer layers 6 - 9 takes place so, at least if the at least two pressure separations on different substrates or polymer layers 6 - 9 are printed and have the same expansion and / or shrinkage properties in a lamination, that the individual pressure separations, ie the printed print separations, in the substrate layer stack 18 are arranged in register over one another.

Subsequently, the substrate layers or polymer layers 6 - 8th respectively. 6 - 9 assembled into a composite body. The joining takes place via a lamination process, which preferably takes place via a hot and cold press 19 is performed. The interconnected substrate layers or polymer layers 6 - 8th respectively. 6 - 9 become a singling unit 20 supplied, which is designed for example as a punch and a security and / or value document 21 , which is a polymer layer composite, for example, punched out and / or cut.

For It will be understood by those skilled in the art that the manufacturing process is here is described in a simplified manner. Of course you can added further process steps and device parts and / or added to the introduction of further security elements and / or security features for a security and / or security Value document are provided. For example, a laser engraving station be provided and / or a hologram in the form of another layer, preferably a developed photosensitive polymer layer be added to the lamination. Explicit are also other, non-digital printing possible, such as offset printing and screen printing, the printing technology security features such as guilloche or bring in OVI colors. The document does not have to be exclusive be printed digitally.

When related to 1 described manufacturing process, the individual substrate layers are supplied in the form of provided on rolls of polymer layers. In another embodiment of the method, the individual polymer layers or substrate layers can be printed and / or gathered in the form of sheets. A register-accurate alignment is preferably carried out via a so-called three-point system of the individual compiled sheets. Prior to the lamination process, in which the individual polymer layers are joined to the composite body, stapling, for example via ultrasonic bonding and / or targeted introduction of laser radiation, can take place locally in one or more locations in individual boundary layers of adjoining substrate layers. Other stapling methods, such as heated staples, can of course be used. A separating step can be omitted if the sheets are precisely matched to the polymer layer composite to be produced.

In 2a is again schematically the structure of a designed as a polymer layer composite value and / or security document 21 represented in which a first information 30 typographically stored in 2 B is shown.

In 2 B is schematically a line of a print image of a first information 30 shown. The pixels 32 become two halves alternately 29 . 31 associated with the two indentations 27 . 28 to 2a result.

For illustrative purposes, print separations are shown greatly enlarged and the individual substrate layers 22 . 23 . 24 shown spaced apart. This applies to all figures described here. In the finished value and / or security document 21 these layers are preferably monolithic far the substrate layers are all made of the same polymer material, materially interconnected. An upper substrate layer surface 25 the substrate layer 23 is with a printout 27 , the first half 29 of the pixels 32 a first piece of information 30 includes, printed. A lower substrate layer surface 26 the substrate layer 23 is accordingly with a second pressure extract 28 printed, the second half 31 of the pixels 32 a first piece of information 30 includes. To the printed partial information of the two pressure separations 28 . 28 to protect against tampering and / or adulteration, are lying outside the substrate layers 22 and 24 intended. In the finished polymer layer composite are the two pressure separations 27 . 28 in different levels of the security and / or value document 21 arranged or imprinted.

At top view on the 2a along a first line of sight 33 becomes the first information 30 played. When viewed under a different viewing direction 34 This results in a color change, since the pixels (pixels) of the first print separation 27 and the second pressure extension 28 partially overlay. Further, pixels 35 at least partially visible, otherwise through the pixels of the first printout 27 in plan view along the line of sight 33 are covered.

As a rule, at least the substrate layers 22 and 23 transparent, preferably also the substrate layer 24 , In one embodiment, one of the substrate layers 22 - 24 translucent, preferably between pressure separations 27 and 28 arranged substrate layer 23 ,

In 3 is a first piece of information 30 flatly shown schematically. The pixels 32 can have any different (basic) colors. The numbers indicated indicate how the pixels alternate along second orthogonal directions 36 . 37 alternately be assigned two pressure extracts.

In 4a is an exemplary decomposition of the first information 30 in three print extracts 41 - 43 shown schematically. Here are the print extracts 41 - 43 monochromatic color separations of a tricolor color space, for example a cyan-magenta-yellow color space. In the from the substrate layers 51 - 54 formed polymer layer composite 40 become the pressure separations 41 - 43 on spaced substrate layer surfaces 56 . 57 . 58 the substrate layers 52 and 54 printed. In plan view along the viewing direction 33 This results in the complete first information. When viewing diagonally from top left along the line of sight 34 However, there is a different view. Also previously hidden areas or pixels 35 the pressure extracts 42 . 43 become visible. In these visible pixels 35 a second piece of information can be stored.

In 4b these pixels are uniformly assigned a background information, which is shown in black. The print extract 43 from the viewing page 50 of the polymer layer composite 40 In one embodiment, a portion of an electronic circuit and / or a microchip (not shown) inserted into the polymer layer composite can be made to be remotely located. As a result, for example, the microchip is protected against unnoticed exchange. Likewise, a diffractive element can be secured.

In 4c another embodiment is shown. In this are each related to an excellent direction 36 the individual pixels that are available for storing the second information are set differently colored according to a color scheme. Such an exemplary color scheme is in 4d partially indicated. Depending on the design of adjacent pixels on the right and left (unprinted or printed with one of the primary colors), the color for the hidden in plan view, possibly set at a different viewing angle, the pixels becoming visible. Missing pixels on the edge are assumed to be non-printed pixels.

It results for the expert that more complex schemes can be used to make a desired Color-tilt effect for the security feature to achieve. For this purpose, for example, an embodiment of the next but one adjacent pixels of the pixels in above and / or below arranged pressure separations, etc. are included.

Likewise, of course, embodiments are advantageously possible, in which in the originally hidden pixels 35 only at one from the top view 33 deviating line of sight 34 becoming visible, a predetermined second information is stored. This information can be obtained, for example, by differentiating two views of the polymer layer composite at predetermined viewing angles (or viewing directions 33 . 34 ) and then preferably evaluated by machine.

The first information and possibly also a predetermined one second information preferably comprise individualizing and / or personalizing information. Likewise, it is beneficial in the first Information color transitions, such as a Iris print, integrate. It may be provided that the pixels of the first color in a printout and the pixels the second color to be printed in a second print separation. However, it is also possible, the pixels in other ways distribute between two or more separations, the printed on different substrate layer surfaces are preferably spaced apart from each other in the formed polymer layer composite are arranged.

In 5 is another embodiment of a polymer layer composite 40 shown at the below the pressure separations 41 - 43 to 4b a lower substrate layer surface 59 the substrate layer 54 with luminescent colorants 60 is printed. The substrate layer surface 59 is preferably printed so that when excited with UV radiation surface white light is emitted. The pixels of the printing extracts 41 - 43 Filter this white light so that the first information is colored in plan view along it's line of sight 33 is visible. At different viewing angles (for example, under the line of sight 34 ) a double filtering takes place, so that again a color change can be observed.

Is one of the substrate layers, between the two of the pressure separations 41 - 43 is arranged, translucent, for example, the substrate layer 53 Thus, in a plan view without UV excitation, another information is visible than when UV excitation. Without UV excitation, only the information parts of the print separations are 41 and 42 visible, noticeable. With UV excitation are also the information portions of the pressure extension 43 visible, noticeable.

Are additionally the substrate layers 51 . 52 and 54 . 55 transparent, so the embodiment after 5 It is assumed that the luminescent colors in the visible wavelength range are transparent.

Of the Transparency can be taken for granted even without the luminescent imprint realize.

at In other embodiments, the luminescent Fabrics even without a printing, for example, in a production one of the substrate layers, introduced into this substrate layer and get over this in the polymer layer composite.

at The described embodiments are the individual Pressure extracts preferably applied by ink jet printing.

at The substrate layers are preferably polymer layers Polycarbonate-based. As the ink is preferably a liquid Preparation used, also prepared on a polycarbonate basis is.
