发明名称 Data carrier, e.g. a banknote, with at least a security marking area to prevent counterfeiting in the form of an optically variable embossed structure with optically varying coatings arranged over the embossed area
摘要 Data carrier has an embossed optically variable structure (2) with raised regions and a coating that is different to the remaining area of the data carrier. The embossed structure and coating are so combined that their appearance varies according to whether they are looked at from vertically above or from an angle - a pivoting effect results. The first coating is only applied in parts, while a second coating with an optically contrasting appearance is applied in other parts, with at least some overlapping partial areas. An Independent claim is made for a method for producing a data carrier an embossed security region.
