Multi-Layer Body and Method for the Production Thereof

The invention relates to a method for the production of a multilayer body, in particular a security element, comprising the following steps:

a) producing a metal layer on a substrate;
b) partial demetalization of the metal layer to form a first item of optical information in a first area of the multilayer body;
c) applying a partial lacquer layer in a second area of the multilayer body to form a second item of optical information, wherein the partial lacquer layer extends at least partially beyond the metal layer;
d) structuring the partial metal layer in the second area using the partial lacquer layer as mask.

The invention further relates to a multilayer body produced in this way.

Multi-Layer Body and Method for the Production Thereof

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.
