SAFETY ELEMENT PROVIDED WITH AN OPTICALLY-VARIABLE LAYER AND METHOD FOR THE PRODUCTION THEREOF

摘要

The invention relates to a safety element for protecting valuable objects comprising an optically-variable layer (20) producing different colour effects when viewed at different angles. According to said invention, a semi-transparent colour layer (34) is disposed in a covering area (32) over the optically variable layer (20), wherein the colour effect produced by said optically variable layer (20) when viewed under predetermined viewing conditions is adapted to the colour effect produced by the semi-transparent colour layer (34) in the covering area.
