Definitions

  • the invention relates to a security document, in particular a bank note, identity card or the like, with a security element which is at least partially provided with a magnetic material, and a method for producing the security document.
  • Magnetic materials can be applied in the form of strips, for example, or can be arranged on separate carrier materials, which in turn are firmly connected to the document.
  • Such a security document is known for example from DE-PS 16 96 245.
  • a suitable carrier material such as e.g. Silk, cotton or plastic are provided with a magnetic coating mixture and then embedded in a security document.
  • the security document can be uniquely identified by machine on the basis of the security element, in particular a security thread.
  • a security document is also known from DE 41 01 301, in which a magnetic security element is introduced, in which the magnetic coating has soft magnetic pigments. These light gray to silvery pigments are mixed in a suitable varnish and spread together with this on a carrier material and then embedded in the security document so that the magnetic security element introduced hardly appears in reflected light.
  • the examination of security documents that have magnetic security elements can, as for example in DE 27 54 267 C3 described, among other things, be carried out so that the coercivity of the element is measured.
  • the object of the present invention is therefore to propose a security document and a method for its production, which comprises a magnetic material whose magnetic properties are designed in such a way that they are difficult to imitate.
  • the basic idea of the invention is to use a carrier as a security element which has been coated with a defined, low-coercive magnetic layer. Because of the low coercivity and the resulting rapid demagnetization even under the influence of weak fields, such magnetic layers do not allow permanent data storage, but they have the advantage over the conventional medium-coercive magnetic coatings that they are unusual in the trade. Because the coercivity of one material is independent of other magnetic Values, for example the remanence, can be set, it is possible to introduce the magnetic materials according to the invention into the document, the magnetic materials differing only in the value of the coercivity from those previously used.
  • iron is used as the magnetic material, which is evaporated onto a carrier.
  • the desired coercivity of the iron layer applied can be set via the production parameters regardless of its thickness. If, for example, the layer is applied in several separate evaporation steps, a lower coercivity is achieved than with continuous evaporation of the entire layer of the same total thickness. Furthermore, the less impurities the material contains, the lower the coercivity.
  • iron layers with the same layer thickness can be produced, which have a uniform remanence but have different coercivities.
  • coatings can also be applied that have a uniform coercivity but different layer thicknesses and thus different remanences.
  • This fact has the advantage that the data carrier with the magnetic material according to the invention can first be examined with standard sensors, for example, to determine whether there are magnetic materials in the data carrier which have a sufficiently large remanence. It can then be checked whether the magnetic material has the coercivity value required for authenticity detection.
  • crystalline, powdery, low-coercive materials which can be mixed into a binder and printed.
  • FIG. 1 shows a bank note 1 with an embedded security thread according to the invention.
  • the thread is completely embedded in the paper interior, which is indicated by the dashed line.
  • the security element can also be incorporated into the value document in the form of planchettes or mottled fibers at certain points in the security document.
  • the security thread according to the invention is shown in cross section along the section line A - B in FIG. 2.
  • a magnetizable iron layer 4 which has a coercivity of 100 Oe, is applied to a carrier 3, which usually consists of a plastic material.
  • the magnetizable layer 4 can also consist of nickel or a magnetic alloy.
  • the only condition is that the coercivity of the layer is between approximately 10 and approximately 250, preferably between 20 and 150 Oe.
  • the thickness of the magnetizable layer has essentially no influence on the coercivity and can be set between 0.05 and 1 ⁇ m with the usual choice of process parameters.
  • Retentions are set, the values of which are preferably between 100 and 1000 nWb / m.
  • the magnetizable material for example iron
  • the layer thickness of the total magnetizable layer is 0.1 ⁇ m.
  • a coercivity of approx. 20 Oe is achieved.
  • the remanence is about 150 nWb / m.
  • the coercivity can be changed by changing the process parameters with the same layer thickness, but the remanence also remains the same.
  • the magnetizable layer with a thickness of 0.1 ⁇ m is evaporated in a single operation, which leads to a coercivity of 100 Oe and a remanence of 150 nWb / m.
  • the same coercivity of 100 Oe with higher remanence can be achieved by increasing the layer thickness to 0.2 ⁇ m and again applying the vapor deposition in a single operation, since the change in the layer thickness does not essentially affect the coercivity.
  • the remanence increases to a value of approx. 300 nWb / m. In this way, layers can be specifically produced which, as a common property, have uniform coercivity with different layer thicknesses, while other magnetic properties, such as remanence, are different for each layer thickness.
  • the magnetic material can be applied, for example, by resistance-heated evaporation of pure iron.
  • the layers can also be produced by anodic arc evaporation or electron beam evaporation. It is also possible to use a printable magnetic material that has a correspondingly low coercivity.
  • Information such as pictures, logos or lettering
  • These can be produced, for example, by preventing the magnetic layer from accumulating in partial areas or by deliberately removing the magnetic layer after application, so that, for example, the thread shown in FIG. 3, which has been provided with the lettering PL, can be produced .
  • the characters 6 are e.g. generated by local removal of the magnetizable iron layer with the aid of a laser beam.
  • other methods can also be used with which the negative characters are embedded in the thread, e.g. the methods described in EP 516 790.
  • a thin metal layer 5 can be applied over the magnetizable layer 4, as shown in FIG. 4.
  • the additional metal layer which consists for example of aluminum, can be applied to the magnetic layer 4 before the characters 6 are introduced, so that the metal layer 5 in this area is also completely removed when the characters are introduced.
  • a metal layer 5 is first applied to a carrier 3, to which the magnetizable layer with low coercivity is applied in a further operation.
  • a further metallic layer 7 is applied to the magnetic layer 4.
  • the information already introduced above and included in the security thread can be in a positive or negative form.
  • the information can also be applied to the surface of the metallic layer 5 or 7 as well as to the surface of the magnetizable layer 4 by means of suitable printing methods, such as microprinting.
  • the security paper is introduced into a testing device.
  • the security document can first be examined for this whether there is a magnetizable security element.
  • any magnetic property can first be determined, for example the remanence is measured. This should have a minimum value that is higher than the retentive values of printing inks that are usually used on the data carrier. Such retentive values are preferably above 100 nWb / m. If this test is positive, the security element is subjected to a further test in which it is checked whether a specific coercivity value can be measured.
  • the authenticity of the document can be verified by comparing the measured coercivity value with a specific value for this document.
  • the first step is not absolutely necessary to be able to check the document. What is essential in the method used in each case is merely the reliable determination of the coercivity value of the security element, it not even being necessary to compare it with any stored values. This is always the case when it is already clear which coercivity value proves the authenticity of the document during the measurement.
