Metodo para producir un portador de datos multicapas, que contiene una primera capa de plastico que comprende un lado superior sobre el cual esta dispuesta una capa opaca, y una segunda capa de plastico dispuesta sobre la primera capa, y en donde la capa opaca es removida parcialmente usando un laser hasta que tenga al menos una hendidura; y portador de datos.

摘要

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.
