Abstract (en)
[origin: WO2022199884A1] The invention relates to an optically variable security element (20) for safeguarding articles of value. The security element has a feature layer (24) containing, in a common plane, first and second feature regions (30, 40) arranged so as to accurately fit together. The first feature regions (30) contain a first embossing lacquer layer of a first embossing lacquer (32) into which an embossed structure (34) that creates a first optical effect has been embossed. The second feature regions (40) contain a second embossing lacquer layer of a second embossing lacquer (42) into which an embossed structure (44) that creates a second, different optical effect has been embossed. The first and second embossing lacquers (32, 42) have different solidification properties and different optical properties. The invention also relates to a production process for such an optically variable security element, and to embossing arrangements comprising a semifinished security element product and means of impressing an embossed structure.
