A method for producing a visually perceptible without technical aids security feature, security feature for plastic-based value or security document and document with at least one such security feature

摘要

A method for producing a security feature visually perceptible without technical aids, comprising the following steps: a) providing a first material layer, b) applying a first lacquer to form a second material layer formed by a first lacquer layer at least in partial regions of the first material layer, wherein the first lacquer layer has a Refractive index, which differs from the refractive index of the first material layer by at least 0.1, and partial curing of the first coating and in a first curing step, c) generating a structuring of the first lacquer layer, the structuring of a feature size parallel to the surface of the security feature of at least 10 microns and perpendicular to the surface of the security feature of at least 5 microns, d) applying a second varnish to form a second varnish layer on the first varnish layer and simultaneous complete curing of both varnishes in one second curing step of the first paint, wherein a curing step of the second paint is identical to the second curing step of the first paint, wherein both paint layers are inseparably connected to each other in the second curing step of the first paint and wherein the security feature thus produced is visually perceptible due to refraction of electromagnetic radiation ,
