A multilayer body and to methods for producing a security element

It is a multi-layer body (1, 2, 3) and a method for producing a security element described. The multi-layer body has a metal layer (21). In a facing or upper side of the multilayer body, the upper side of the multilayer body forming the first surface of the metal layer (21) and / or forming in a facing or bottom of the multilayer body, the bottom of the multilayer body second surface of the metal layer (21) is at least partially an optically active surface relief shaped. In at least one first region (31 to 39) of the multilayer body is formed, the surface relief from a first relief structure (61). The first relief structure (61) has in at least one by an associated azimuth angle determined direction (617) a sequence of elevations (612) and recesses (614) which sequences whose elevations (612) with a period P one another which is smaller than a wavelength is the visible light, wherein the minima of the recesses (614) lying on a base surface and the first relief structure (61) has a relief depth t, which by the spacing of the maxima of the projections (612) of the first relief structure (61) from the base surface in a plane perpendicular to the base surface direction is determined. reflected the profile shape and / or the relief depth t of the first relief structure (61) is chosen such that the colored appearance of the first area (31 to 39) under at least incident a first angle of incidence and of the metal layer (21) in the first region directly or through the metal layer directly transmitted light is changed (53 52), in particular by plasmon resonance of the metal layer with the incident light is changed.
