Multi-Layer Body and Method for the Production Thereof |
摘要 |
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. |
