用于制造多层数据载体的方法以及通过所述方法制造的数据载体
摘要：
本发明涉及一种用于制造多层数据载体的方法以及通过所述方法制造的数据载体，所述数据载体包含由塑料制成并具有顶面的第一层，在所述顶面上布置有部分地覆盖该顶面的不透明层，例如金属层。所述数据载体具有由塑料制成的第二层，其布置在第一层上并且至少在所述金属层的子区域上是透明的。用激光部分地移除所述金属层，直到所述金属层具有至少一个缺口。所述金属层优选地层叠在第一塑料层和第二塑料层之间。
摘要（英）：

The method involves partially carrying an opaque layer i.e. metal layer, with laser, where the opaque layer comprises an aperture or is made of a material. The opaque layer is changed during radiation in such a manner that the opaque layer is transparent or translucent at a radiated region. The opaque layer is laminated between two plastic layers, and a data carrier (1) is manufactured with two metal films (2), which are arranged parallel together. The metal films are attached to an opaque core film in a window, where the plastic layers comprise thickness of 50 micrometer. An independent claim is also included for a multilayered data carrier.
