摘要

In order to ensure the authenticity and / or authenticity of a security or security document, a security feature which can be visually perceived without technical aids, a value or security document having such a security feature and a method for producing such a security feature and a security document having such a security feature created. The security feature 10 is formed by a first material layer 11 and a first resist layer 12, wherein the first resist layer 12 has a structuring and wherein the first resist layer 12 has a refractive index which differs by at least 0.1 from the refractive index of the first material layer 11. The security feature 10 is visually perceptible due to refraction of electromagnetic radiation without technical aids. The method of production is such that the security feature 10 according to the invention can be introduced into the document during production or can subsequently be applied to a surface of a document blank.
