Security element, manufacturing method, data carrier equipped with the security element and method for verifying the authenticity

摘要

The invention relates to a security element for a data carrier, in particular a document of value, comprising a carrier substrate, the front side of which has a macroscopic motif composed of a large number of microscopic individual elements, wherein: the microscopic individual elements each contain at least three adjacent areas produced by printing technology, which are so designed that the viewer perceives a so-called first light-medium-dark contrast under first viewing conditions within each individual element, perceives an essentially uniform brightness under each second element under second viewing conditions and a so-called second light-medium-dark within each individual element Perceives contrast that is inverted compared to the first light-medium-dark contrast; and the microscopic individual elements in the viewer with an oscillating change between the first and the third viewing conditions produce a dynamic impression of the macroscopic motif and the first, second and third viewing conditions are defined as follows: first viewing conditions: viewing when illuminated with visible light; second viewing conditions: viewing when lighting with a combination of visible light and ultraviolet light in substantially equal parts; third viewing conditions: viewing when illuminated with ultraviolet light.
