  • 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 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 Druckaustool 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. Under at least a second, different viewing angle results in at least one color change.
  • a security feature is created by printing technology, which is easy to verify, but is not duplicated by a copy operation.
  • 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.

  • 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 piece of information can not be reproduced with a single ink.
  • multicolored information is considered if it causes at least two color impressions in a viewer, with differences in brightness here should not represent different color impressions.
  • colored information is considered, which causes more than three different color impressions, of which preferably at least one color impression caused by additive color mixing (in luminescent colors) or subtractive color mixing (in so-called body colors) of primary colors that span a color space, or caused can be.
  • the first information comprises a colorful or multi-colored personalizing facial image of a person.
  • a printed image embodied by the first information is decomposed into pixels and each pixel exactly one of at least two indentations is assigned. The assignment is thus made so that each pixel is assigned to exactly one printout. In embodiments in which more than the at least two pressure separations are used, this means that each pixel is assigned to exactly one of the several print separations.
  • print separations are printed multiple times but with register accuracy on different substrate layer surfaces, preferably spaced apart in the composite body, in order, for example, to obtain a better opacity.
  • a pixel here has only one ink in all printouts.
  • the print separations are hierarchically sorted with respect to their spacing in the polymer layer composite from an upper viewing side (front), with a lowest hierarchical level assigned to the print separation furthest from the viewing side and the print separations modified by pixels of the print separations to which no pixel is assigned, but the corresponding pixel is assigned to a print separation of a higher hierarchical level, a pixel is assigned to a second information.
  • the print separations are thus assigned at those points pixels of the second information, which by a pixel of the first information on an overlying substrate layer surface of the substrate layer stack or one above lying plane of the composite are concealed in a vertical plan view.
  • the second information can be formed here as desired.
  • the pixels of the second information all have a uniform color. These pixels of the second information are or will be printed in white or black opaque or blanket.
  • the second information may be colored and derived from the first information or completely independent.
  • the second information is derived as a function of the pixels of the first information in the individual pressure excerpts. If a pixel of a print separation, which is covered in plan view by a pixel of the first information arranged above it, has an adjacent pixel which represents a pixel of the first information, then one color can be assigned to the first information depending on the color of the neighboring pixel be so that the most pronounced color effect in a tilting of the substrate layer composite, d. H. when changing the viewing direction, occurs.
  • Particularly reliable color change effects can be achieved if, at least with respect to a selected direction, preferably with respect to two mutually orthogonal directions, adjacent pixels are respectively assigned to different print separations. Immediately adjacent pixels along the excellent direction are thus always associated with different pressure separations. Preferably, along a second direction orthogonal to the excellent direction, there are also no immediately adjacent pixels of the first information assigned to the same print separation. The pixels will be for example, alternately along the excellent direction associated with the two pressure extracts.
  • luminescent means are introduced in such a way that when UV excitation takes place
  • White light is emitted and the substrate layer surface or substrate layer below at least one, preferably all, which is arranged at least two printing extracts in the document body produced.
  • UV radiation stimulates white fluorescence. This includes light of different wavelengths, which causes a white color impression via a color addition.

  • There is a double filtering which usually causes a change in hue or at least a change in the brightness of a hue.
  • An independently inventive embodiment of a polymer layer composite with a viewing angle-dependent security feature is obtained by printing the first information, which is preferably individualizing and / or personalizing, onto a substrate layer surface and onto a substrate layer surface underlying it in the polymer layer composite or below it Substrate layer on or introduces luminescent agent.

This would be completely absorbed by some colors, but transmitted by others, so that it can produce a viewing angle-dependent luminescence. It is also possible to use different luminescent colors and place them next to, above, or with each other in order to combine the effects with one another. On top of each other, this means a vertical distance in different substrate layers, together a true mixture, which can give a white luminescence, or occupy another part of the spectrum.
