  • An underlying security feature of the data carrier can be recognized visually and/or by machine through these gaps.
  • a data carrier in the form of a data page is known, which is constructed in multiple layers.
  • This data page includes a flap which forms an overhang in relation to 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 fleece strip and a printed sheet arranged therewith, which are connected to one another by transparent cover layers arranged on their outside.
  • Customary paper pages or biaxially suitable polypropylene are used for the production of the personal data page, which are provided with polycarbonate foils on both sides.
  • a data carrier such as a banknote, known, which consists of a security paper.
  • a film application element in patch form is provided on this security paper.
  • This includes a transparent central window area. Below this central window area of the foil application element, a translucent area is formed in the security paper by the action of a substance such as concentrated sulfuric acid.
  • the combination of the transparent window area of the film application element with the translucent area of the bank note results in an area that appears bright in transmitted light inside the window area of the film application element.
  • a security element such as a banknote is known.
  • This includes a substrate made of a material that essentially includes 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 includes free areas in which a translucent ink is applied.

  • the data page consists of a laminate in which a flap is inserted between several layers and fixed by the lamination.
  • the EP 1 502 765 A1 discloses a personalized data page of a passport in which a flexible layer is provided with a polymer layer on both sides.
  • Such data sheets or data carriers have the disadvantage that manipulations of printed images, for example by covering, sticking over, painting over, cannot be detected without a more detailed check.
  • the invention is based on the object of creating a multi-layer composite which enables simple detection of a manipulation of a printed image. Furthermore, the invention is based on the object of proposing a method for its production, which makes manipulation of a printed image more difficult. Furthermore, the invention is based on the object of proposing a value and/or security document with further increased security against manipulation.
  • a multi-layer composite as defined in claim 1 is proposed. Due to the at least partial or at least area-wise impregnation of the fibrous layer with the melt of the hot-melt adhesive patch, the light-scattering property of the fibrous layer is reduced depending on the melt, so that opaque areas of the fibrous layer can be converted into partially translucent areas or translucent areas by the melt. This allows a Create see-through feature.
  • the printed image can not only be viewed from the data side in reflected light, but is also made visible via the title page.
  • the printed image can preferably be visible in reflected light from the title page, so that the printed image can be viewed from its back.
  • the printed image can become visible in transmitted light due to the impregnation of the fiber layer with the melt.
  • This see-through feature thus makes it possible for any manipulations on the data page by pasting over, covering or painting over the printed image to be easily detected from the title page, since the deviations from the printed image then become obvious.
  • Print image is understood to mean a printed reproduction that is structured in some way or covers the entire surface.
  • a structured print reproduction for example, an image such as a passport photo or portrait or a graphic print reproduction such as guilloches or background screening or alphanumeric characters or a one- or two-dimensional barcode, emblem, coat of arms, national emblem or any other print reproduction can be considered.
  • the opacity of the fiber layer can be changed by introducing the quantity or the proportion of the melt in a predetermined area or at a predetermined point in the fiber layer.
  • By increasingly filling the interstices in the fiber layer with a preferably clear melt increasing transparency can be created, so that not only are transition areas between opacity and partial transparency possible, but complete transparency can also be achieved. In this case, the fiber layer is completely saturated by the melt.
  • the fiber layer is advantageously impregnated with a transparent melt produced from the hot-melt adhesive patch and has fibers with a refractive index that are approximately the same or identical to the refractive index of the melt of the hot-melt adhesive patch. Due to the When the melt is introduced into the fiber layer, air displacement between the individual fibers of the fiber layer is achieved in the introduced area, so that the air pockets no longer cause light to be scattered and a semitransparent or transparent or translucent effect can thus be set and achieved.
  • At least the area of the fiber layer covered by the printed image is at least partially impregnated in the two-dimensional direction of extent of the data sheet and completely over the thickness of the fiber layer of the melt produced from the hot-melt adhesive patch.
  • the impregnation of the melt can run along the line structure, so that only the line structure is visible in transmitted light and possibly also in reflected light.
  • a covered area can also be completely filled with the melt by a full-surface portrait.
  • the melt forms an outer edge around the flat printed image.
  • targeted darkening or brightening by means of such a melt can also be used to protect individual areas of the printed image.
  • the at least one layer made of a polymer is preferably transparent. This makes it easier to view the printed image from the title page in both transmitted and reflected light.
  • this further layer on the title page can also be only partially transparent or have darkenings in the area of the printed image in order to achieve certain superimpositions or completions of the image in interaction with the printed image in order to detect manipulations more easily with the eye without technical aids.
  • the fiber layer can be made from a random arrangement of natural and / or synthetic fibers exist, such as a flat Fiber bundles, a fiber network, a flat fiber arrangement, in particular a fleece, a felt, a paper or a cellulose-containing layer.

  • the fiber layer can consist of natural fibers, synthetic fibers and a mixture of natural and synthetic fibers.
  • the melt of the hot-melt adhesive patch can 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 result in an additional increase in security against forgery.
  • the fiber layer is preferably thinned out in this area.
  • the fibrous layer may include thinned areas in the form of lines or areas. Squares and/or circles can be produced in a planar or linear manner.
  • the thinned out areas are preferably generated by addition watermarks.
  • a print image or data is printed into the thinned area, in particular using an inkjet method, and at least this area is filled with the hot-melt adhesive patch, so that at least this thinned area becomes transparent.

  • the multi-layer composite preferably comprises a fiber layer with perforations, in which connecting webs are formed when the fiber layer is connected to the layers.

  • security-relevant areas as, for example, portraits or optically active security features or the like can be additionally secured.
  • the object on which the invention is based is also achieved by a method defined in claim 11 for producing a multi-layer composite.
  • a local or partial impregnation of the fiber layer by means of a melt can create an individual design of a see-through feature that is diverse in terms of structure and construction, shape or geometry and can be adapted to the printed image.

This allows additional anchoring between the layers. Attempting to detach the layers from the connecting webs can lead to cracks, which form an optically active security feature.
  • the diameter or the minimum width of the perforation holes in the fiber layer is determined depending on the thickness of the layer made of thermoplastic polymer and the thickness of the layer is 0.5 to 1.5 times the diameter or the minimum width of the perforation holes, or the diameter or the minimum width of the connecting bars.
