Patent ID: 8557369

Claim:
A security element for marking the authenticity of objects of value, said security element comprising: a substrate and at least one micro-optic authenticity feature provided on said substrate, the micro-optic authenticity feature comprising a first micro-optic arrangement with a multiplicity of focusing elements which are present in a first grid, and a second micro-optic arrangement with a multiplicity of microstructures which are present in a second grid, the first and second arrangements being disposed such that the microstructures of the second arrangement are observable as magnified upon viewing through the focusing elements of the first arrangement, wherein the first and/or second micro-optic arrangements comprise a polymeric material and are produced from a highly refractive embossing lacquer which contains at least one binding agent which has at least one radiation-curing compound comprising one or more organic compounds, at least a portion of said organic compounds of the radiation-curing compound comprising molecules with at least one polarizable element, so that the radiation-curing compound is configured to form a polymeric material with a refractive index of greater than 1.5 upon radiation curing of the radiation-curing compound.
