A security element with effect pigments and an embossed structure and process for its preparation

2015 
The invention relates to a valuable and security document consisting of a substrate having a front side and a back side, wherein on the front or back of the substrate, a color layer is applied. In the ink layer a first design in the form of a pattern, character or a coding is incorporated. The first motif is embodied in the form of an embossing structure consisting of a plurality of raised embossing elements having surfaces of different orientation and, upon tilting of the value and security document indicates a first tilting or movement effect by using at least two different sets of embossing elements having different characteristic parameters incident light in different spatial areas reflect. The embossing elements each have a lateral dimension greater than 30 microns and a height of more than 10 microns. The invention further relates to a method for producing a corresponding value or security document. According to the invention, the first motif with a second pattern in the form of a pattern, character or coding is combined, wherein the second motive is disposed on the same side of the substrate as the first subject. The second design is embodied in the form of an embossing structure consisting of a plurality of raised embossing elements having surfaces of different orientation. The embossing pattern forms the second subject with a second tilt or movement effect by having different characteristic parameters reflect different groups of embossing elements incident light into different spatial regions. Here, the embossing elements each have a lateral dimension of less than 30 microns and a height of less than 10 microns. In addition, the patterns, the character or the coding of the first pattern at least partially on the pattern, the character or the coding of the second motif is adjusted.
