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.

Abstract: A method for producing a multilayer body, with the steps of: a) providing a substrate film with a replication layer; b) molding a surface relief appearing to the observer in the form of a three-dimensional free-form surface, which is formed in particular by structures with a lens-like design generating a magnifying, demagnifying or distorting effect, into a surface of the replication layer; c) applying a first metal layer to the surface of the replication layer forming the surface relief; d) wet-chemically applying an at least partially transparent spacer layer to the metal layer; e) applying a second metal layer to the spacer layer.

Abstract: A method for forming a volume hologram film having security elements which are formed as a transfer section of the volume hologram film is described, wherein the volume hologram film has n volume hologram layers arranged one over another. The production of the volume hologram film is carried out in a roll-to-roll method with the following method steps: a) providing a carrier film from a supply roll; b) applying an i-th photopolymer layer to the carrier film; c) forming an i-th volume hologram in the photopolymer layer; d) forming an i-th volume hologram layer by curing the i-th photopolymer layer; e) repeating process steps b) to e) n−1 times; f) applying an adhesive layer to the background layer; g) winding the volume hologram film onto a take-up roll.

Abstract: A method for producing security elements, security elements, a security document with at least one security element as well as a transfer film with at least one security element wherein a three-dimensional object is recorded and a surface profile of the three-dimensional object, described by a function F(x,y), is determined, wherein the function F(x,y) describes the distance between the surface profile and a two-dimensional reference surface spanned by co-ordinate axes x and y at the co-ordinate points x and y. A first microstructure is determined in such a way that the structure height of the first microstructure is limited to a predetermined value smaller than the maximum distance between the surface profile and the two-dimensional reference surface, and the first microstructure provides an observer with a first optical perception which corresponds to the surface profile of the three-dimensional object described by the function F(x,y).

Abstract: A method for producing a security element formed as a lenticular flip, including a micro-optical layer, a carrier substrate and an image layer, wherein the image layer includes n images for n=1 to i which are visible from an n-th observation angle allocated to the n-th image, and wherein n is at least 1. The images are imaged on a photoresist with parallel light in contact print or by means of projection. After the photoresist is developed, an image layer which includes the i images is present.

Abstract: A system (100, 200, 300, 400, 500, 600) for producing a security element (4), in particular a vignette for a windshield (6) of a means of transport, is specified. This comprises a carrier element (3) with a first and a second surface, wherein a first sub-element (1) of the security element (4) is arranged in a first area (31) of the first surface and a second sub-element (2) of the security element (4) is arranged in a second area (32) of the first surface separated from the first area (31) by a fold edge (33). These sub-elements (1, 2) can be made to overlap with the first sub-element (1) by folding of the carrier element (3) along the fold edge (33) and can be adhered by means of an adhesive (25) arranged on the side of the second sub-element (2) facing away from the carrier element (3). An individualization feature (14) can be attached to a side of the first (1) and/or the second (2) sub-element facing away from the carrier element (3). Furthermore, a method for producing a security element (4) by means of such a system (100, 200, 300, 400, 500, 600), as well as a security element (4) obtained thereby, is specified.
