发明名称 PRODUCTION OF A SECURITY ELEMENT PROVIDED WITH COLORED MICRO-DEPRESSIONS
摘要 A method for producing a security element having microdepressions for security papers, with the microdepressions being colored with a certain color, involves the steps of (a) coating an upper side of a carrier with an embossable layer; (b1) forming microdepressions in the embossable layer to configure an embossed layer; (c) applying the certain color on the upper side, so that the color remains in the microdepressions; (b2) applying a structured protective layer on the coated upper side, wherein the structured protective layer does not cover the microdepressions that are to be colored with the certain color, after step (b1) and before step (c); and removing the structured protective layer and thereby a color toning after step (c).
