Abstract: A method for the production of a multilayer body, in particular a security element, includes: 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.

Abstract: 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.

Abstract: A document with an embossed macroscopic structure and acting through optical diffraction is disclosed. The structure, which serves as a security element comprises a plurality of surface portions with predetermined relief structures having spatial frequencies of over 10 lines/mm. Each surface portion is different from directly adjoining surface portions and at least some of the surface portions have a maximum dimension of less than 0.3 mm. To the naked eye, the pattern of surface portions on the document appears as a mesh of dots and lines. However, to an examiner with a magnifying device, the dots and lines appear as numbers, characters or other graphic features.
