Patent ID: 10105982

Abstract:
A security element for securing security papers, value documents and other data carriers, has a lenticular image that, from different viewing directions, displays at least two appearances. The lenticular image includes a lens grid composed of a plurality of microlenses and a laser-sensitive motif layer arranged spaced apart from the lens grid. The laser-sensitive motif layer comprises, in two or more motif layer sub-regions, different markings introduced by the action of laser radiation and that, when the motif layer is viewed with the lens grid, produce at least two appearances. The lens grid is divided into two or more lens grid sub-regions in which the microlenses each comprise differently refractive lens surface forms. The different lens grid sub-regions are congruent with the different motif layer sub-regions, and the markings of the motif layer sub-regions being produced by laser impingement of the lens grid sub-regions.
