Abstract

The invention relates to a method for producing a multi-layer body, in particular a security element, in which a partial first layer or partial first layer system is produced on a substrate, wherein the partial first layer or partial first layer system is present in a first partial area and not in a second partial area. Subsequently, a partial second layer or partial second layer system is produced, wherein the partial second layer or partial second layer system is present in a third partial area and not in a fourth partial area, and wherein the third partial area overlaps with the first and second partial areas. Finally, the partial first layer or partial first layer system is structured as a mask using the partial second layer or partial second layer system.
