Abstract:
A security element in the form of a multi-layer film body with a security element and a process for the production of such a security element. The film body has a replication lacquer layer and a thin-film layer for producing a viewing angle-dependent color shift effect by interference. A first relief structure is shaped in a first region in the interface between the replication lacquer layer and the thin-film layer. That relief structure suppresses the production of the color shift effect by the thin-film layer so that the color shift effect is not present in the first region in which the first relief structure is provided and the color shift effect produced by the thin-film layer is present in a second region of the security element, in which the first relief structure is not provided.
