Abstract:
A multilayer body ( 1, 2, 3 ) and a method for producing a security element are described. The multilayer body has a metal layer ( 21 ). An optically active surface relief is molded at least in areas in a first surface of the metal layer ( 21 ) facing the upper side of the multilayer body or forming the upper side of the multilayer body and/or in a second surface of the metal layer ( 21 ) facing the underside of the multilayer body or forming the underside of the multilayer body. In at least one first area ( 31  to  39 ) of the multilayer body the surface relief is formed by a first relief structure ( 61 ). In at least one direction ( 617 ) determined by an allocated azimuth angle, the first relief structure ( 61 ) has a sequence of elevations ( 612 ) and depressions ( 614 ), the elevations ( 612 ) of which follow on from each other with a period P which is smaller than a wavelength of visible light, wherein the minima of the depressions ( 614 ) lie on a base surface and the first relief structure ( 61 ) has a relief depth t which is determined by the spacing of the maxima of the elevations ( 612 ) of the first relief structure ( 61 ) from the base surface in a direction perpendicular to the base surface. The profile shape and/or the relief depth t of the first relief structure ( 61 ) is chosen such that the colored appearance of the light ( 52, 53 ) incident on the first area ( 31  to  39 ) at least at a first angle of incidence and directly reflected by the metal layer ( 21 ) in the first area or directly transmitted through the metal layer is modified, in particular is modified by plasmon resonance of the metal layer with the incident light.

Claim (Index 15):
The security element according to  claim 1 , wherein the surface relief in one or more second areas and/or further areas is formed by a second relief structure which is or are selected from the group: diffractive relief structure, holographic relief structure, mirror surface, mat structure, macrostructure, lens, grid of microlenses.
