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 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: An optically variable element has first and second diffraction gratings which are high-frequency and therefore act reflectively into the zero diffraction order. Either a first color is generated by the first diffraction grating at a particular angle of rotation and a particular angle of illumination and simultaneously a second color, different from the first color, is generated by the second diffraction grating or a visible color is generated essentially only by the first diffraction grating at a first angle of rotation and a visible color is generated essentially only by the second diffraction grating at a second angle of rotation.

Abstract: A multilayer body includes a transparent first layer. In the transparent first layer, a multiplicity of microlenses arranged in accordance with a microlens grid are impressed in a first region. Furthermore, the multilayer body includes a second layer, which is arranged below the first layer and in a fixed position with respect to the first layer and has a multiplicity of microimages arranged in accordance with a microimage grid and in each case in an at least regional overlap with one of the microlenses of the microlens grid for the purpose of generating a first optically variable information item. The grid pitches of the microimage grid and of the microlens grid in each case in at least one spatial direction are less than 300 μm.

Abstract: A decorative element (2), in particular in the form of a transfer film, a laminating film or a security thread, as well as a security document with a decorative element and a method for producing same is described. The decorative element (2) has a microstructure (4) which generates an optical effect in incident light and/or with light passing through. In a first area (32), the microstructure (4) has a base surface (40) and several base elements (41) which have in each case an element surface raised or lowered compared with the base surface (40) and a flank arranged between the element surface and the base surface (40). The base surface (40) of the microstructure defines a base plane spanned by coordinate axes x and y. The element surfaces of the base elements (41) in each case run substantially parallel to the base plane. In at least one or more first zones of the first area (32), the element surfaces of the base elements (41) and the base surface (40) are spaced apart in a direction running perpendicular to the base plane (40) in the direction of a coordinate axis z by a first distance which is chosen such that a color is generated in the one or more first zones in particular by interference of the light reflected at the base surface and the element surfaces in incident light and/or in particular by interference of the light transmitted through the element surfaces and the base surfaces with light passing through.
