Abstract

The invention relates to a data sheet (1) for integration in a preferably book-like security and/or valuable document, wherein the data sheet (1) is formed of at least two stacked layers (2, 3) of an organic polymeric material, wherein at least in a partial section between the layers (2, 3) and outside of the layers (2, 3), a paper material layer (5) forming a flap (4) is disposed, and wherein the paper material layer (5) is coated and/or wet through on one or both sides at least in the region between the layers (2, 3) at least partially with an organic binding agent (6), and is bonded with the two layers (2, 3) by means of the binding agent (6).

First claim

The invention claimed is:

1. A data sheet for integration in a book-like security and/or valuable document,
wherein the data sheet is formed of at least two stacked layers of an organic polymeric material,
wherein at least in a partial section between the layers and outside of the layers, a paper material layer forming a flap is disposed,
wherein the paper material layer is wet through at least in the region between the layers with an organic binding agent and is bonded with the two layers by means of the organic binding agent, and
wherein the organic binding agent is a polycarbonate derivative; and

wherein the paper material layer is a multi-layer structure and includes at least one low-absorbent middle layer, and on either side of the middle layer and connected therewith one absorbent outer layer each, the paper material layer being wet through with the organic binding agent in the area between the layers and/or outside of the layers substantially exclusively in the outer layers.

2. The data sheet according to claim 1 , wherein the organic polymeric material is selected from the group consisting of PC (polycarbonate, in particular bisphenol A polycarbonate), PET (polyethylene terephthalate), PMMA (poly(methyl methacrylates)), TPU (thermoplastic polyurethane elastomers), PE (polyethylene), PP (polypropylene), PI (polyimide or poly-trans-isoprene), PVC (polyvinyl chloride), polystyrene, polyacrylates and methacrylates, vinyl esters, ABS and copolymers such as polymers, cycloolefin copolymers, polysulfones, polyesters, PET, PEN, polycarbonate/polyester blends, e.g., PC/CoPET, polycarbonate/polycyclohexyl methanol cyclohexane dicarboxylate, in particular polycarbonates or copolycarbonates based on diphenols, poly- or copolyacrylates, poly- or copolymethacrylates, poly- or copolymers with styrene, thermoplastic polyurethane, polyolefin, poly- or copolycondensates of the terephthalic acid or naphthalene dicarboxylic acid or mixtures thereof, particularly preferred polycarbonates or copolycarbonates based on diphenols, poly- or copolyacrylates, poly- or copolymethacrylates, poly- or copolycondensates of the terephthalic acid or naphthalene dicarboxylic acid or mixtures thereof.

3. The data sheet according to claim 1 , wherein the organic binding agent is a polycarbonate based on bisphenol A.

4. The data sheet according to claim 3 , wherein the organic binding agent is a polycarbonate based on geminally disubstituted dihydroxy-diphenyl cycloalkane.

5. The data sheet according to claim 1 , wherein the paper material layer is substantially homogeneous and absorbent in the direction perpendicularly to the main faces, the paper material layer being wet through with the organic binding agent.

6. The data sheet according to claim 1 , wherein the binding agent ( 6 ) and/or the paper material layer ( 5 ) additionally contains one or a plurality of substances or materials from the group consisting of color pigments, effect pigments, optically variable pigments, and luminescent substances or pigments, and/or one or more security features from the group consisting of watermarks, biluminescent fibers, planchettes, security threads, and window threads.

7. The data sheet according to claim 1 , wherein in or on the paper material layer, at least one electronic circuit with an antenna connected thereto is disposed.

8. The data sheet according to claim 1 , wherein the paper material layer includes on or in the stacked layers at least one watermark.

9. A method for preparing a data sheet according to claim 1 , comprising the steps of:
providing two layers of an organic polymeric material and a paper material layer,
applying on at least partial sections of one side of a layer or of both layers and/or on partial sections of one side or of both sides of the paper material layer a coating of a liquid uncured binding agent,
stacking the layers and the paper material layer on each other and disposing with the coated sides facing each other with the proviso that part of the paper material layer projects as a flap outside of the two layers,
laminating the layers and the paper material layer to each other, and
curing or crosslinking the binding agent.

10. The method according to claim 9 , wherein the flap is provided with the binding agent or does not include the binding agent.

11. The method according to claim 9 , wherein the paper material layer is disposed in a partial section only between the layers.

12. A security and/or valuable document including a data sheet according to claim 1 , wherein the data sheet is included by means of the flap in a binding back.

13. A security and/or valuable document including a data sheet according to claim 1 , wherein the data sheet is included by means of the flap in a binding back that is sewn or glued therein.
