    Abstract: The invention relates to a security element (1). The security element (1) has a visible face, and a rear side lying opposite said face. The security element includes at least one luminous layer (2), which can emit light (20), and at least one mask layer (4), which is arranged in front of the at least one luminous layer (2) when looking at the security element (1) from the visible face. The at least one mask layer (4) has at least one opaque region (5) and at least two transparent openings (41, 42). The at least two transparent openings (41, 42) have a significantly higher degree of transmission than the at least one opaque region (5) with respect to the light emitted (20) by the at least one luminous layer (2), preferably a degree of transmission higher by at least 20%, with a degree of transmission higher by at least 50% being especially preferred.

    Abstract: The invention relates to a multilayer body (1, 2, 3) and a method for producing a security element. The multilayer body has a metal layer (21). An optically active surface relief is formed on at least some regions of a first surface of the metal layer (21), said first surface facing the top of the multilayer body or forming the top of the multilayer body, and/or a second surface of the metal layer (21), said second surface facing the bottom of the multilayer body or forming the bottom of the multilayer body. The surface relief is formed by a first relief structure (61) in at least one first region (31 to 39) of the multilayer body. The first relief structure (61) has a sequence of elevations (612) and depressions (614) in at least one direction (617) determined by a corresponding azimuth angle, said elevations (612) successively following one another with a period P which is smaller than a visible light wavelength. 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 distance between the maxima of the elevations (612) of the first relief structure (61) and 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 selected such that the coloration of the light (52, 53) which is incident on the first region (31 to 39) at at least one first angle of incidence and which is directly reflected by the metal layer (21) in the first region or directly transmitted through the metal layer is changed, in particular by means of the plasmon resonance of the metal layer together with the incident light.
