Abstract: A security element for securing security papers, value documents and other data carriers, includes a lens grid image with a lens grid of a plurality of micro lenses and a radiation-sensitive motif layer arranged at a distance from the lens grid. The radiation-sensitive motif layer includes, in one motif region, a multiplicity of transparency regions produced by the action of radiation. The radiation-sensitive motif layer has, at least in the motif region, a color partial layer and a contrast partial layer. The color partial layer includes chromophore effect pigments which appear to be colored against the background of the contrast partial layer and which appear to be transparent without a contrast layer.

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.
