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 32):
The security element according to  claim 1 , wherein the concentration of the dyes or luminescent substances in the area of the first or second layer less than 500 nm, away from the first or second surface of the metal layer is higher than in the remaining area of the first or second layer.
