Data storage card and method for the manufacture of a data storage card
First Claim
1. A data carrier card comprising a card body comprising:
- one or several foils, wherein the foil or at least one of the several foils comprises a single coextruded foil layer having at least two contiguous surface areas that are co-planar having different material properties,wherein at least one first surface area of the at least two surface areas of the coextruded foil is opaque and at least one second surface area of the at least two surface areas of the coextruded foil is transmissive, andwherein the at least one first surface area is formed entirely of a first material having at least one material property that is different than the at least one second surface area, said at least one first surface area and said second surface area being arranged to form at least a top surface of the single coextruded foil layer.

Abstract
A data carrier card and a method for producing a data carrier card, in particular a chip card or magnetic stripe card. The data carrier card has a card body having one or several foils, where the foil or at least one of the foils is a coextruded foil having at least two areas with different material properties. The use of coextruded foils makes it possible to form in a simple manner different areas in the card body which differ from each other in material quality. In particular, it is possible to form for example a data carrier card with a card body having a plurality of alternating opaque and transmissive strips or with window strips and/or windows enclosed in the surface of the card body.

- 17. A method for producing a data carrier card comprising a card body comprising one or several foils, wherein the foil or at least one of the several foils comprises a single coextruded foil layer having at least two contiguous surface areas that are co-planar having different material properties, wherein at least one first surface area of the at least two surface areas of the coextruded foil is opaque and at least one second surface area of the at least two surface areas of the coextruded foil is transmissive, said method comprising the step forming the card body by coextrusion of at least one foil such that the at least one foil has at least two contiguous surface areas with different material properties, wherein the at least one first surface area is formed entirely of a first material having at least one material property that is different than the at least one second surface area, said at least one first surface area and said second surface area being arranged to form at least a top surface of the single coextruded foil layer.
