A method for producing a multilayer body with the steps of a) applying a first varnish layer made of a water-based photoresist to a surface of a base body; b) exposing the first varnish layer in a first region, wherein the first varnish layer is not exposed in a second region; c) removing the first varnish layer in the second region.

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.

Disclosed is a method for manufacturing a multilayer data medium having reflecting metallised inscriptions (23) visible from at least one outer surface (11). A basic pattern (24) is imprinted onto a transparent impression layer (21), the pattern being selected so as to be able to receive the inscriptions (23), to be transparent and to have a surface tension of more than 40 dynes/cm and a smooth surface condition with specular reflection of more than 50% measured according to the ISO 2813 standard at an angle of 60, and no glass-transition temperature in the rolling temperature range; then the inscriptions (23) are imprinted in contact with the basic pattern (24), and then hot rolling under pressure of a stack including the impression layer (21) is carried out.
