Definitions

  • the invention relates to a layer structure, a value document with a layer structure and a method for producing a value document.
  • Valuable documents in the sense of the invention include banknotes, shares, bonds, certificates, vouchers, checks, air tickets, high-quality admission tickets, product security labels, credit or cash cards, but also other documents prone to forgery, such as passports, identification cards or other identification documents.
  • Valuable documents are usually made from paper substrates that have special security features, such as have a security thread at least partially incorporated into the paper and a watermark.
  • Paper substrates are usually made from natural polymer, such as cotton fibers, synthetic polymer, such as polyamide fibers, or combinations of natural and synthetic polymer (s).
  • documents of value can also be made entirely of synthetic polymer.
  • documents of value can be constructed, for example, in multiple layers.
  • a document of value may have a document of value substrate made of natural polymer, wherein after applying various security features, foils / layers of synthetic polymer are applied to / on this document of value substrate.
  • Security features usually provide special tactile and / or optically perceptible effects.
  • Tactile security elements can be tactile embossments or reliefs, for example.
  • Optical security elements can be holograms or color shift effects, for example.
  • DE 10 2009 053 925 A1 uses a slat structure in a security element to completely block or unblock the view of a motif depending on the viewing angle through the - optionally metallized - slats (blind effect).
  • DE 10 2010 047 250 A1 In a surface, randomly varying reflective facets are described pixel by pixel in an area.

The reflection regions preferably cover 50% of the surface of the relief. The reflection areas are preferably opaque reflection areas.
  • the distributed mirror surfaces are formed by the combination of reflection areas and the relief.
  • the display of the mirror surfaces can be released, and the display is therefore visible to an observer.

  • the expression "a representation on a main surface of the value document substrate” can be understood to mean a representation applied to or on a main surface. According to one embodiment, this can include that the means for forming the representation, such as printing inks, at least partially penetrate into the value document substrate. According to an alternative embodiment, the means for forming the representation do not penetrate the value document substrate, but are only in surface contact with at least one of the main surfaces.
  • a multiplicity of distributed mirror surfaces on a main surface, which cover the representation, the representation being suppressed by the distributed mirror surfaces as a function of a viewing angle is to be understood in particular to mean that the representation between one of the main surfaces of the value document substrate and the layer element or the plurality of distributed mirror surfaces is arranged. In other words, the plurality of distributed mirror surfaces is arranged in a thickness direction over the representation.
  • the layer structure preferably comprises a carrier substrate.
  • the distributed mirror surfaces are preferably arranged on / above the carrier substrate.
  • the representation is preferably arranged between the carrier substrate and the distributed mirror surfaces.
  • the carrier substrate arranged between the representation and the distributed mirror surfaces.

Furthermore, further relief elements preferably have a deviation between 0 ° and 15 ° from the specified angle of inclination. Alternatively or additionally, the further relief elements have a deviation between 0 ° and 15 ° from the fixed azimuth angle.

  • a deviation based on the azimuth angle can be understood to mean the difference between the azimuth angle of the relay element with a medium orientation and the azimuth angle of the relay element with a different azimuth angle.
  • the angle of inclination of the surface normal of a relief element with a medium orientation can be 35 °.
  • a relief element with a deviation of 3 ° from this central orientation (35 °) can then have an angle of 32 ° or 38 ° to the surface normal.
  • the azimuth angle of the surface normal of a relay element with a medium orientation can be 0 °.

  • a relief element with a deviation of 3 ° from this central orientation (15 °; 40 °) then shows e.g. an angle of inclination of 12 ° or 18 ° or an azimuth angle of 37 ° or 43 °.

  • the azimuth angle of the first group and the azimuth angle of the second group differ by at least 5 °, particularly preferably by at least 10 °.
  • the viewing angles of two groups advantageously differ. As a result, part of the display covered by a first group is released to a viewer at a certain viewing angle, while another part of the display covered by a second group is suppressed by a viewer from this specific viewing angle.
  • the display or the areas of the display that are / are covered by several groups of the distributed mirror surfaces are suppressed or released at different viewing angles.

  • the relief elements which have the reflection regions 406 form the distributed mirror surfaces.
  • the reflection areas can here preferably be applied by means of vapor deposition processes, for example vapor deposition processes.

  • metal particles are present in a binder as so-called flakes.
  • This metal particle dispersion or flakes can be applied, for example, by means of a printing process. The flakes are so thin that they adapt to the structure of the relief or follow it.
  • reflection areas can be generated by structuring a (homogeneous) reflection layer by selective removal by means of an etching process.

  • the reflective layer 506 on the ridges 504a can be removed by separation wrapping.
