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 decorative element (2), in particular in the form of a transfer film, a laminating film or a security thread, as well as a security document with a decorative element and a method for producing same is described. The decorative element (2) has a microstructure (4) which generates an optical effect in incident light and/or with light passing through. In a first area (32), the microstructure (4) has a base surface (40) and several base elements (41) which have in each case an element surface raised or lowered compared with the base surface (40) and a flank arranged between the element surface and the base surface (40). The base surface (40) of the microstructure defines a base plane spanned by coordinate axes x and y. The element surfaces of the base elements (41) in each case run substantially parallel to the base plane. In at least one or more first zones of the first area (32), the element surfaces of the base elements (41) and the base surface (40) are spaced apart in a direction running perpendicular to the base plane (40) in the direction of a coordinate axis z by a first distance which is chosen such that a color is generated in the one or more first zones in particular by interference of the light reflected at the base surface and the element surfaces in incident light and/or in particular by interference of the light transmitted through the element surfaces and the base surfaces with light passing through.
