Abstract

There is proposed a multilayer card-shaped data carrier ( 1 ) having a core layer ( 2 ) based on paper, with an individualization ( 5 ) formed in said layer. At least a part of the area of the data carrier ( 1 ) is deformed into a relief ( 10 ) which has a viewing angle-dependent optical effect and which extends into the core layer ( 2 ) through the cover layer ( 4 ).

First claim

1 . A multilayer card-shaped data carrier ( 1 ) having a core layer ( 2 ) and a cover layer ( 4 ), characterized in that
at least a part of the area of the data carrier ( 1 ) is deformed into a relief ( 10 ) which additionally has a superimposed viewing angle-dependent optical effect and which extends into the core layer ( 2 ) through the cover layer ( 4 ).

2 . The data carrier according to claim 1 , characterized in that the relief ( 10 ) has at least one punch-through ( 19 ) on which the residual material thickness of the core layer ( 2 ) amounts to between 33% and 0%, preferably between 30% and 10%, based on the thickness (D) of the data carrier ( 1 ).

3 . The data carrier according to claim 1 , characterized in that the core layer ( 2 ) is based on paper and has an individualization ( 5 ).

4 . The data carrier according to claim 1 , characterized in that the relief ( 10 ) is produced by an embossed print.

5 . The data carrier according to claim 1 , characterized in that the structure depth of the relief ( 10 ) corresponds to 20 to 100% of the total thickness of the data carrier ( 1 ), preferably 30 to 60%.

6 . The data carrier according to claim 1 , characterized in that the cover layer ( 4 ) carries in the region of the relief ( 10 ) an optically variable element ( 7 ) which is deformed in accordance with the relief ( 10 ).

7 . The data carrier according to claim 1 , characterized in that the relief ( 10 ) includes a part of the individualization ( 5 ).

8 . The data carrier according to claim 1 , characterized in that it has a protective layer ( 8 ) on the opposing side of the cover layer, and the deformation also includes the protective layer ( 8 ).

9 . The data carrier according to claim 1 , characterized in that another part of its area is likewise deformed into a relief whose structure depth is different from that of the relief ( 10 ) and has another optical effect.

10 . A method for manufacturing a multilayer card-shaped data carrier ( 1 ) having a core layer ( 2 ) and a cover layer ( 4 ) having the steps of
supplying a core layer ( 2 ) based on paper, supplying a cover layer ( 4 ), forming an individualization ( 5 ) in the core layer ( 2 ) and/or in the cover layer ( 4 ), connecting the cover layer ( 2 ) with the core layer ( 4 ),
characterized by the following further steps:
deforming at least a part of the area of the cover layer ( 2 ) and of the core layer ( 4 ) into a relief ( 10 ) which additionally has a superimposed viewing angle-dependent optical effect and which extends into the core layer ( 2 ) through the cover layer ( 4 ).

11 . The method according to claim 10 , characterized in that the connection of core layer ( 2 ) and cover layer ( 4 ) is effected by lamination, and the deformation into a relief ( 10 ) happens upon the laminating operation.

12 . The method according to claim 10 , characterized in that the core layer ( 2 ) is embossed upon deforming at least at one place up to a residual material thickness of 33% to 0%, preferably 30% to 10%, based on the thickness (D) of the data carrier ( 1 ).
