发明名称 SECURITY ELEMENT WITH COLOR SHIFT EFFECT AND MAGNETIC PROPERTIES, OBJECT WITH SUCH A SECURITY ELEMENT AS WELL AS METHOD FOR PRODUCING THE SECURITY ELEMENT AND THE OBJECT
摘要 A security element (1) for application or embedding in objects (300), in particular for documents of value such as bank notes, credit cards and the like, is structured in a multi-layer fashion and has an interference element I, which produces a color shift effect, a layer M with magnetic properties and a reflection layer R, which is located between interference element I and magnetic layer M. Designs of the invention provide a negative writing 20 and/or coding 11 in reflection layer R and magnetic layer M. According to a further design diffraction structures 2 are integrated in the security element 1. Such a security element in particular is suitable as window security thread 200 in bank notes.
