Security document i.e. passport, has film body fixed at carrier layer, where structure of carrier film is changed in one set of zones of film body with respect to another set of zones of film body for reducing rigidity of carrier film

摘要

The security document (1) has a film body (10) fixed at a carrier layer (20) by an adhesive layer (21). The film body includes a carrier film (11) and electrically conductive layers (12, 13), where a structure of the carrier film is changed in a set of zones (31) of the film body with respect to another set of zones (32) of the film body for reducing rigidity of the carrier film. The electrically conductive layers are made of a metal layer with layer thickness between 0.1 micrometer and 1 micrometer. The document is in the form of a booklet with multiple sheets (24). An independent claim is also included for a method for producing a security document i.e. passport.
