SECURITY FEATURE FOR A VALUE AND/OR SECURITY PRODUCT, VALUE AND/OR SECURITY PRODUCT HAVING THE SECURITY FEATURE AND METHOD FOR PRODUCING THE SECURITY FEATURE

摘要

In order, for example, to be able to individualize an optically refractive structure, which forms a security feature for a product of value and/or security product 100, a modified security feature 200 is developed, which comprises the following features: (a) the security feature 200 comprises at least one optical element 210, which is formed from a material having a first refractive index n1, and (b) the at least one optical element 210 comprises optically refractive structures 220, at which radiation S, incident on the security feature 200 from a surrounding medium L with a second refractive index n2, is refracted or at which structures radiation S already entered into the at least one optical element 210 is subjected to total internal reflection. For individualization purposes, the at least one optical element 210 is superposed with a structuring medium 235 in at least one pattern-forming region 240.
