Description
;PHOTOSENSITIVE IMA~E RECIEVING SHEET MATERIAL
BACKGROUND OF THE INVENTION
Field of the invention The present invention relates to a transfer sheet 5 employable as color proof for use in color proofing or display, and more particularly relates to a photosensi-tive image receiving sheet material suitable for use in an image forming process which comprises transferring a transferable image formed on a temporary support to an 10 image receiving sheet material and then re-transferring said image to a permanent support.
Description of prior art There is known an image transfer process which com-prises exposing a photosensitive laminate compo~ed of a 15 peelable layer consisting of an organic polymer and a photosensitive resin layer provided on a temporary sup-port to light, developing it to form an image on the peelable layer and transferring the image onto a given suppo`rt (i.e., permanent support) by using an adhesive 20 (see, Japanese Patent Publications No. 46(1971)-15326 and No. 49(1974)-441). This process had advantages in that it can be used as color proof for various procedures such as of overlay type, surprint type, etc. However, that process has disadvantages in that an a~hesive has to be 25 used for every transferring operation and hence the pro-cess is complicated and in that there is a difficulty in keeping the accuracy of registration in transferring each colorO
To eliminate the complication of the process, there are proposed processes wherein after the formation of an image, the image is laminated to a permanent support under the application of heat and pressure (see, Japanese 5 Patent Provisional Publications No. 47(1972)-41830, No.
48(1973)-9337 and NoO 51(1976)-5101)~ Particularly, Japanese Patent Provisional Publication No. 51(1976)-5101 discioses that a hot-melt polymer layer as an adhesive is provlded on a permanent support and Japanese Patent Pro-10 visional Publication No. 47(1972)-41830 discloses that an image is laminated directly to a permanent support such as art paper or coated paper.
However, these processes still have various disad-vantages in that the final image is laminated to a perma-15 nent support in such a manner that the right and the leftare reversed against the original image and in that when a hot-melt polymer is used as an adhesive, the melting point thereof is usually high and hence the transferring temperature has to be high so that the dimensional stabi-20 lity of the support is lowered by the influence of heat,and the deviation of colors from one another in registra-tion is caused in transferring each color. ~hen a hot-melt polymer having a low melting point is used as an ad-hesive, there are the problems that after the formation 25 of an image, sticking is caused, or the surface thereof is liable to be marred.
As a process for eliminating the above-described disadvantages, there is proposed in Japanese Patent Pro-visional Publication No. 59(1984)-97140 a process wherein 30 an image is laminated to a temporary image receiving sheet be~ore the image is laminated onto a permanent sup-port. This process includes steps of: preparing a tempo-rary image receiving sheet provided with an image receiv-ing layer composed of a photopolymerizable material on a 35 support; transferring an image of each color onto the 3 _ temporary image receiving sheet before the image of each color-is laminated to a permanent support; re-transfer-ring said image onto a permanent support; and exposing wholly it to light to cure the laminated photopolymeriz-5 able image-receiging layer.
The above-described image transferring process using the temporary image receiving sheet (hereina~ter referred to simply as image receiving sheet) is very effective in eliminating the aforementioned problems. In more detail, 10 there are the following advantages. An erect image cor-responding to the masked original image can be formed on the permanent support. Since an ethylenically unsatu-rated polyfunctional monomer serving as a photopolymeriz-able substance is incorporated in the photopolymerizabl~-15 image receiving layer of the image receiving sheet, thephotopolymerizable image-receiving layer itself is soft, transferring can be carried out at a low temperature and after transferring, it can be exposed wholly to light to cure it. In more detail, there are the advantages that 20 after the trans~er of the image, sticking is not caused and the final image has high resistance to marring.
In the image receiving sheet employed in the process of the Japanese Patent Provisional Publication No.
59(1984)-97140, adhesion between the photopolymerizable 25 image receiving layer (that is, photopolymerizable adhe-sive layer) and the support is very high in the unexposed state. Therefore, when the photopolymerizable adhesive layer having a received image is laminated to the final support and the support for the image receiving material 30 is peeled off before the exposure operation, peel marks (that is, linear crack produced on the photopolymerizable adhesive layer due to~excessive shock brought about by the peeling operation, or stain given by a portion of the adhesive layer remaining on the surface of the image-35 receiving layer) are liable to be formed on the surface of the laminated image-containing photopolymerizable adhesive layer. Hence, in the process of the Japanese Patent Provisional Publication No. 59(1984)-97140, the image-containing photopolymerizable adhesive layer is 5 laminated to the ~inal support and the whole is exposed to light to cure the photopolymerizable adhesive layer.
At the same time, adhesion between the photopolymerizable adhesive layer and the support of the image receiving sheet is lowered and the support is removed.
Though the above-described image transferring pro-cess is effective in obtaining the final image of high quality, the present inventors have found that said process should be improved on the following problems.
When a support having high surface smoothness is 15 used as a support for the image receiving sheet in said image transferring process using an image receiving sheet, the surface of the final image laminated to a permanent support is glossy. On the other hand, when a color proof for color proofing is to be prepared utiliz-20 ing the image transferring process, it is necessary thatthe surface of the color proof is roughened to allow it to approximate to the surface of a print. Roughening is generally performed using a process wherein an appropri-ate mat film is laminated on the surface of the final 25 image and then the surface of the image is matted by heating under pressure.
In order to mat the surface of the final image formed on the permanent support by the procèss stated in the Japanese Patent Provisional Publication No. 59(1984)-- 30 97140, a mat film is placed on the cured (i.e., hardened) adhesive layer, and heat and pressure must be applied to the surface. High heat and high pressure are required for the matting of the surface of the image, and the final image is liable to suffer deterioration ~nder such 35 severe conditions.
s In other problems, when a photosensitive material which is a positive type and releases nitrogen gas during photolysis such as naphthoquinone diazide is used in the transferable photosensitive image forming material, naph-5 thoquinone diazide is decomposed and nitrogen gas isreleased in curing the photopolymerizable adhesive layer by light exposure. Nitrogen gas stays at the interface between the image part and the cured adhesive layer.
Thus, when a subsequent high-temperature matting treat-10 ment is carried out, the interface is deformed by expan-sion of the nitrogen gas and the quality of the image is deteriorated.
In summary, it is desirable that the matting of the surface of the image is carried out in such a manner that 15 while the image receiving layer is still soft (that is, before the photopolymerizable material of the photopoly-merizable image receiving layer together with image placed on the permanent support is cured), and an appro-priate mat film is placed on the surface of the image and 20 the surface of the image is matted by heating under pres-sure. However, there is a problem that peel marks are formed on the surface of the image receiving layer in removing the support for the image receiving sheet from the laminated photopolymerizable image receiving layer as 25 described above.
SUMMARY OF THE INV~NTION
It is an object of the present invention to provide a photosensitive image receiving sheet suitable for use in performing an image forming process comprising trans-30 ferring a transferable image formed on a temporary sup-port to an image receiving sheet material and then re-transferring said image to a permanent support.
There is provided by the present invention a photo-sensitive image receiving sheet material comprising a photopolymerizable adhesive layer provided on a support via a peelable organic high-molecular polymer layer.
The photosensitive image receiving sheet material of the invention is suitable for use in the above-described improved image forming process wherein after an image laminated onto the photopolymerizable adhesive layer of the image receiving sheet material is re~laminated to a 10 permanent support, the support for the image receiving material is removed by utilizing the peelable organic high-molecular polymer layer prior to light exposure pro-cedure (i.e., curing operation~ and then the matting procedure and exposure procedure are carried out.
Accordingly, there is the advantage that when the photosensitive image receiving sheet material of the present invention is used, there can be effectively pre-vented lowering in the quality of image which is caused in the course of the roughening (matting) of the surface 20 of the image in the image forming process (or image transferring process) including steps of transferring an image from a temporary support to an image receiving sheet and re-transferring the laminated image to the final support. When the above-described improved process 25 is used, there is an additional advantage that the mat-ting of the surface of the image can be easily conducted at a relatively low temperature and under low pressure, because the surface of the photopolymeri7able adhesive layer is still in a soft state before exposure.
DETAILED DESCRIPTION OF THE INVENTION
As the support for the image receiving sheet materi-al, a transparent support having high dimensional stabi-lity under a high temperature condition is pre~erred.
Examples of such support include polyethylelne terephtha-late *ilm and polycarbonate films. However, the supports which can be employed in the invention are not limited thereto.
The surface of the support for the image receiving sheet material may be treated by releasing agents, corona discharge or glow discharge so that adhesion between said support and the high~molecular polymer layer is made higher than that between the temporary support and the 10 image forming layer directly formed on the temporary support, while said adhesion between the support and the polymer layer is made lower than that between the re-laminated im~ge forming layer and the permanent support in re-transferring the image onto the permanent support.
Examples of material~ which can be used for the pre-paration o~ the peelable organic high-molecular polymer layer of the invention include polyole~ins such as poly-ethylene and polypropylene; ethylene copolymers such as copolymers oi~ ethylene and vinyl acetate and copolymers 20 of ethylene and acrylate; polyvinyl chloride; vinyl chlo-ride copolymers such as copolymers of vinyl chloride and vinyl acetate; polyvinylidene chloride; vinylidene chlo-ride copolymers; polystyrene; styrene copolymers such as copolymers of styrene and a maleate; poly-(meth)acryl-25 ates; (meth)acrylate copolymers such as copolymers o~ a(meth)acrylate and vinyl acetate; vinyl acetate copoly-mers; polyvinyl acetal resins; gelatin; modified poly-vinyl alcohols; polyamide resins such as nylons (poly-amides), copolymer nylons and N-alkoxymethylated nylons;
30 synthetic rubber; chlorinated rubber; and cellulose deri-vatives, Among them, there are preferred polyvinyl chlo-ride, vinyl chloride copolymers, polyvinylidene chloride, vinylidene chloride copolymers, poly(meth)acrylates, (meth)acrylate copolymers, vinyl acetate copolymers, 35 polyvinyl acetal resins and polyamide resins.
~$~. ~S
The above-described organic high-mulecular polymers may be used either alone or as a mixture of two or more of them. Further, an additive such as adhesion improver may be added to the organic high-molecular polymer layer.
Thickness of the peelable organic high-molecular polymer layer is in the range of preferably about 0.1 to 4 ~m, more preferably about 0.5 to 2 ~m. When the organ-ic high-molecular polymer layer is too thick, there is a difficulty in performing matting in due ~orm, though the 10 photopolymerizable adhesive layer to be provided thereon is still in a soft state, while when the polymer layer is too thin, there is a possibility that monomers which are contained in the photopolymerizable adhesive layer oozes out to the surface of the organic high-molecular polymer 15 layer and that the surface of the polymer layer becomes sticky.
A photopolymerizable adhesive layer is provided on the organic high-molecular polymer layer. Any of conven-tional photopolymerizable adhesives or their functionally 20 equivalent compositions may be used for the formation of the photopolymerizable adhesive layer of the invention.
Typical examples of the photopolymerizable adhesives include photopolymerizable materials containing at least one organic high-molecular polymer, an ethylenically un-25 saturated poly-functional monomer having a boiling point of 150C or higher under atmospheric pressure, and a photopolymerization initiator. Examples of such photo-polymerizable adhesives are disclosed in more detail in the Japanese Patent Provisional Publication No. 59(19~4)-30 g7140.
The photosensitive image receiving-material of the present invention can be used in the conventional image forming processes and image transferring processes.
The photosensitive image receiving material of the present invention is suitable for use in the improved image forming process described in the Japanese Patent Provisional Publication No. 59(1984)-971qO wherein an 5 image laminated to the photopolymerizable adhesive layer of the image receiving sheet material is re-larninated to the permanent support, the support for the image receiv-ing sheet material is removed from the photopolymerizable adhesive layer by utilizing the peelable organic high-10 molecular polymer layer before the light exposure proce-dure (i.e., curing procedure), and the matting treatment and the exposure procedure are then performed.
The exposure procedure can be performed according to the teaching of the Japanese Patent Provisional Publi-15 cation No. 59(1984)-97140. The matting treatment can be carried out by the conventional process. In the process using the photosensitive image receiving sheet material of the present invention, the matting treatment is per-formed at a temperature of preferably 20 - 180C, more 20 preferably 60 to 140C and at a presseure of preferably 0.1 to 20 kg/cm2, more preferably 0.1 to 10 kg/cm2.
