  • card-shaped data carriers such as check cards, access cards, identity cards or the like are known, which consist of a multi-layer structure, in particular a multi-layer composite.
  • security features are proposed for such data carriers, such as guilloches, watermarks, embossing marks, fürlichtpasser, holograms or the like. These are intended to make it more difficult or even impossible to forge a counterfeit.
  • a data carrier in the form of a data page is known, which is designed to be multi-layered.
  • This data page comprises a tab which forms a projection against the data page in order to sew the data page into a security and / or value document.
  • the data page is formed by a multi-layer structure, which comprises a nonwoven strip and a printing sheet arranged thereon, which are connected to one another by transparent cover layers arranged on the outside thereof.
  • a disk such as a banknote, known, which consists of a security paper.
  • a foil application element in patch form is provided on this security paper.
  • a translucent area in the security paper is formed by the action of a substance, such as concentrated sulfuric acid.
  • the combination of the transparent window region of the film application element with the translucent region of the banknote produces a region that appears bright in transmitted light in the interior of the window region of the film application element.
  • a security element such as a banknote
  • This comprises a substrate made of a material which essentially comprises paper based on natural and / or synthetic fibers.
  • a first layer is applied to one side of the substrate which serves as an impregnation and comprises free areas into which a transparentizing ink is applied.
  • the data page consists of a laminate in which a tab is inserted between several layers and fixed by lamination.
  • the EP 1 502 765 A1 discloses a personalized data page of a passbook in which a flexible layer is provided on both sides with a polymeric layer.
  • Such data sheets or data carriers have the disadvantage that manipulations on printed images, which can not be recognized, for example, by masking, pasting over, overpainting, without a more accurate inspection.
  • the invention has for its object to provide a multi-layer composite, which allows easy detection of manipulation of a printed image. Furthermore, the invention has for its object to propose a method for its production, which makes manipulation of a printed image difficult. Furthermore, the invention has for its object to propose a value and / or security document with a further increased security against manipulation.
  • the defined in claim 1 multi-layer composite is proposed. Due to the at least partial or at least partial impregnation of the fiber layer with the potting compound, the light-scattering property of the fiber layer is reduced as a function of the potting compound, so that opaque areas of the fiber layer can be converted by the potting compound into partially transparent areas or translucent areas. This can create a visual feature.
  • the print image can not only be viewed from the data side in reflected light, but is also made visible on the front page. In this case, the printed image may preferably be visible in reflected light from the title page, so that the printed image can be viewed from the rear side thereof.
  • Print image is understood to mean a structured or full-surface print reproduction in any manner.
  • a structured print reproduction for example, an image, such as a passport photograph or portrait or a graphic print reproduction, such as guilloches or a background grid or alphanumeric characters or a one or two-dimensional barcode, emblem, crests, national emblems or any other print reproduction, come into consideration.
  • the opacity of the fiber layer can be changed.
  • Increased backfilling of the interstices in the fiber layer with a clear potting compound can provide increasing light transmission, so that not only are transition areas between opacity and partial transparency permissible, but complete transparency can also be achieved. In this case, a complete saturation of the fiber layer is given by the potting compound.
  • the fibrous layer is impregnated with a transparent potting compound and has fibers with a refractive index which is approximately equal to or identical to the refractive index of the potting compound. Due to the incorporation of the potting compound in the fiber layer an air displacement between the individual fibers of the fiber layer is achieved in the introduced area, so that no light scattering occurs through the air inclusions and thus a semi-transparent or transparent or translucent effect can be adjusted and achieved.
  • At least the region of the fiber layer covered by the printed image is at least partially saturated in the planar direction of extent of the data sheet and completely over the thickness of the fiber layer with a potting compound.
  • the impregnation of the potting compound can run along the line structure, so that only the line structure is visible in the transmitted light and possibly also in reflected light.
  • a covered area can be completely covered by a full-surface portrait with the potting compound.
  • the potting compound forms an outer edge around the flat print image.
  • targeted hedging can also be made possible by individual areas of the printed image on targeted darkening or brightening by means of such a potting compound.
  • the potting compound may consist of a thermoplastic polymer, such as UV or thermally crosslinking acrylate, one- or two-component PUR, transparent hot melt adhesives or a thermoplastic. Likewise, it is also possible to use thermoplastic polymers which have a low viscosity at the processing temperature (PEtg).
  • the potting compound is preferably made of a clear or crystal clear material.
  • the at least one layer of a polymer is transparent.
  • this additional layer on the title page may also be only partially transparent or have darkening in the area of the printed image, in order to achieve specific superimpositions or completions of the image in interaction with the printed image in order to detect manipulations more easily with the naked eye without technical aids.
  • the fibrous layer may consist of a random arrangement of natural and / or synthetic fibers, such as a sheet Fiber bundles, a fiber network, a flat fiber arrangement, in particular a nonwoven, a felt, a paper or a cellulose-containing layer.
  • the fibrous layer can also be an aligned array of fibers, such as a woven, knitted, knitted, braided, stitchbonded or textile fabric.

  • the potting compound may contain materials from the group consisting of color pigments, effect pigments, optically variable pigments and / or luminescent substances or pigments or fluorescent substances or pigments. This can be given an additional increase in the security against counterfeiting.
  • the fiber layer is thinned in this area to improve the transmitted light effect in the introduction of the security feature by impregnation.
  • the fibrous layer may comprise thinned areas in the form of lines or areas. Squares and / or circles can be generated in a flat or linear manner.
  • the thinned areas are generated by attachment watermarks.
