Abstract

A card body for a data carrier comprises at least a first and a second foil. The first foil comprises a first light-conducting areal region of a light-conducting material and a first opaque areal region of an opaque material adjoining the first light-conducting areal region. The second foil comprises a second light-conducting areal region of a light-conducting material adjacent to a second opaque areal region. The first and second foils are arranged lying one above the other areally. The first and second foils are aligned such that the first and second light-conducting areal regions form an overlap region. The card body comprises a first cover foil configured to be opaque and arranged above the first foil. The transition from the first and second light-conducting areal regions to the first and second opaque areal regions has light-scattering particles.

Claims

1-16. -16. (canceled)

17. A card body for a data carrier, wherein the card body comprises at least a first and a second foil, the first foil comprises a first light-conducting areal region of a light conducting material and a first opaque areal region of an opaque material adjoining the first light-conducting areal region, the second foil comprises a second light-conducting areal region of a light conducting material which is adjacent to a second opaque areal region, the first foil and the second foil are arranged areally lying one above the other and the first and the second foil are aligned such that the first light-conducting areal region and the second light-conducting areal region form an overlap region;

wherein

the card body comprises a first cover foil, wherein the first cover foil is configured to be opaque and is arranged above the first foil, and

a transition from the first and second light-conducting areal region to the first and second opaque areal region has light-scattering particles.

18. The card body according to claim 17, wherein the first and/or second opaque areal region adjoining the first light-conducting areal region and/or adjoining the second light-conducting areal region comprises light-scattering particles.

19. The card body according to claim 17, wherein the first foil and/or second foil is a co-extruded first and/or second foil.

20. The card body according to claim 17, wherein a concentration of light-scattering particles in the first opaque areal region and/or in the second opaque areal region is smaller in the transition than in regions of the first and/or second opaque areal region which are disposed further away from the transition to the first and/or second light-conducting areal region.

21. The card body according to claim 17, wherein the card body has a second cover foil which is configured to be opaque.

22. The card body according to claim 17, wherein the card body has a light feeding region for feeding light into the first light-conducting areal region and/or into the second light-conducting areal region.

23. The card body according to claim 21, wherein the light feeding region is arranged in the first light-conducting areal region and/or in the second light-conducting areal region.

24. The card body according to claim 21, wherein the light feeding region is arranged in the first and/or second cover foil.

25. The card body according to claim 21, wherein the light feeding region comprises an internal light source and/or a light-conducting connection to an external light source.

26. The card body according to claim 17, wherein the first and/or second cover foil in the overlap region is configured to be partially transparent.

27. The card body according to claim 17, wherein the first and/the second light-conducting areal region comprises color pigments and/or light-scattering particles.

28. The card body according to claim 17, wherein above the overlap region a symbol is arranged which is distinguished optically from the card body by excitation with light from the overlap region, in particular backlighting.

29. The card body according to claim 17, wherein the opacity of the first and second opaque region is greater than the opacity of the first cover foil.

30. An inlay for a partial card body of a data carrier, which, under the action of light, produces an effect that is visible through a first cover foil of a card body, wherein from a light feeding region light is conducted in the partial card body in a light conductor in a longitudinal extension and the light is deflected at a material region.

31. The inlay according to claim 30, wherein the material region extends along the light conductor and extends adjoining said light conductor.

32. The inlay according to claim 30, wherein the inlay is inserted in a card body and/or forms a card body for a data carrier, wherein the card body comprises at least a first and a second foil, the first foil comprises a first light-conducting areal region of a light conducting material and a first opaque areal region of an opaque material adjoining the first light-conducting areal region, the second foil comprises a second light-conducting areal region of a light conducting material which is adjacent to a second opaque areal region, the first foil and the second foil are arranged areally lying one above the other and the first and the second foil are aligned such that the first light-conducting areal region and the second light-conducting areal region form an overlap region;

wherein

the card body comprises a first cover foil, wherein the first cover foil is configured to be opaque and is arranged above the first foil, and

a transition from the first and second light-conducting areal region to the first and second opaque areal region has light-scattering particles.
