Problems solved by technology

The outer surface of the card body is easily scratched during handling, whereby the card body loses its translucent optical properties
Also, strip foils can be duplicated and thus counterfeited as a security feature

Embodiment Construction

[0037] exist Figures 1a to 1c In , the first embodiment of the present invention is shown by the card body. Figure 1a is the exploded view of the card body, Figure 1b is a perspective view. Figure 1c is a plan view of the first foil overlay of the card body.

[0038] The card body 1 is configured as a flat shape. As an example of such an embodiment, the card body 1 comprises a first foil 10 and a second foil 20 . In this case, the first foil 10 is configured as a strip and is produced, for example, by coextrusion. It comprises three strips arranged side by side with each other, namely a first light-guiding planar area 11 and two first opaque planar areas 13 adjacent to the first light-guiding planar area 11 on both sides in the longitudinal direction. The first opaque planar area 13 is arranged next to and adjacent to the first light guiding planar area 11 . The first light guiding plane area 11 and the two first opaque plane areas 13 are arranged on the same first pl...

Abstract

The invention relates to a card body (1) for a data carrier and an inlay for a part of the card body of the data carrier. The card body (1) comprises at least a first film and a second film (10, 20). The first film (10) includes a first light-guiding planar region (11) made of light-guiding material and a first opaque planar region (13) made of opaque material adjacent to the first light-guiding planar region (11). The second film (20) includes a second light-guiding planar region (21) of light-guiding material, the second light-guiding planar region (21) being adjacent to a second opaque planar region (23). The first film (10) and the second film (20) are stacked on each other in a planar manner. The orientation of the first and second films (10, 20) is such that the first light guiding planar region (11) and the second light guiding planar region (21) form an overlapping region (100). The card body (1) also includes a first coating (30). The first covering film (30) is opaque and arranged above the first film (10). Transition regions (14, 24) from the first and second light-guiding planar regions (11, 21) to the first and second opaque planar regions (13, 23) have light-scattering particles.

Description

technical field [0001] The invention relates to a card body for a data carrier and an inlay for a part of the card body. Background technique [0002] Different foils (eg holograms) can be applied to the card-like data carrier as an anti-counterfeiting authenticity feature of the data carrier. Moreover, the light transmission of the card body can also be used as an anti-counterfeiting feature. The card body may comprise a strip of foil. The strip foil is constructed with transparent foil strips, adjacent to which opaque foil strips are arranged. Graphical elements are arranged above the strip-shaped foil, which are recognizable in transmitted or incident light. [0003] The card body is subjected to different stresses during daily use, such as mechanical stress or thermal stress. The outer surface of the card body is easily scratched during handling, whereby the card body loses its translucent optical properties. Furthermore, strip foils may be duplicated and thus count...
