发明名称 SECURITY ELEMENT FOR A DATA CARRIER, DATA CARRIER COMPRISING SUCH A SECURITY ELEMENT SEMIFINISHED PRODUCT FOR PRODUCING A DATA CARRIER, AND METHOD FOR PRODUCING A DATA CARRIER
摘要 The security element has a pattern, and in particular a Moire pattern (10, 11, 16) which contains a coded pattern or image which is made visible through a filter (12,13). The filter (12, 13) is arranged on a layer (3, 3’. 3") that is fixedly connected to a substrate (2, 2', 2") whereby distance of at least 0.025 mm exists between the pattern (10, 11, 16) and the filter (12,13). When the security element (7, 8, 9) is tilted, the pattern or the image moves continuously. The pattern (10, 11.16) is preferably a band Moire pattern. The filter is preferably a line filter that is laser-permeable. The pattern (10, 11, 16) is preferably produced by means of a laser. The security element (7, 8, 9) according to the invention is distinguished by high security against forgery and can nevertheless be produced in a comparatively cost-effective manner.
