发明名称 SECURITY ELEMENT, METHOD FOR PRODUCING SAME, AND DATA CARRIER EQUIPPED WITH THE SECURITY ELEMENT
摘要 The invention relates to a method for producing a security element, comprising the steps of: a) providing a support which has an embossing lacquer layer that has a first, diffractive structure-forming relief structure, and a second, micromirror arrangement-forming relief structure; b) imprinting the first, diffractive structure-forming relief structure with a printing ink which is based on metallic platelet pigments that are designed in such a way that they spatially align themselves along the relief structure of the embossing lacquer layer; c) imprinting with a soluble wash ink such that the regions of the first, diffractive structure-forming relief structure and the second, micromirror arrangement-forming relief structure form recesses in the applied wash ink; d) applying a colored thin-film element over the whole surface and then washing off the wash ink such that the colored thin-film element remains in the regions of the first, diffractive structure-forming relief structure and the second, micromirror arrangement-forming relief structure in a fashion spatially aligned along the respective relief structure; and e) applying an adhesive layer.
