  • Patent number: 11400748
    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.
