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: In a process for producing a multilayer body, an HRI layer made of a material having a high refractive index is applied to at least part of the surface area of a substrate. At least one partial region of the HRI layer is then physically removed from the substrate again by treatment with an alkaline solution. Additionally specified is a multilayer body that can be obtained by such a process.

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.

Abstract: The invention concerns a film element having a replication layer (43), wherein an optically active surface structure (27) is shaped in a first surface of the replication layer. The surface structure is formed in at least a first region of the film element (35) by a first diffractive surface relief (46) comprising a plurality of successive elements following a first envelope curve (47), wherein the elements respectively comprise an element surface (48) arranged substantially parallel to a base surface and at least one flank adjoining the adjacent element surface or surfaces, the element surfaces (48) of adjacent elements are spaced in a direction perpendicular to the base plane, with a first optical spacing or a plurality of the first optical spacing, wherein the first optical spacing is between 150 nm and 800 nm, preferably between 150 nm and 400 nm. The first envelope curve (47) has a spatial frequency of between 100 L/mm and 2000 L/mm and an optical depth of more than 450 nm and the relief shape and the spatial frequency of the envelope curve (47) are so selected that the incident light is diffracted into one or more first directions to represent a first item of information, the color value of which is further determined by the first optical spacing.

Abstract: The invention relates to a method for producing a multi-layer body, in particular a security element, in which a partial first layer or partial first layer system is produced on a substrate, wherein the partial first layer or partial first layer system is present in a first partial area and not in a second partial area. Subsequently, a partial second layer or partial second layer system is produced, wherein the partial second layer or partial second layer system is present in a third partial area and not in a fourth partial area, and wherein the third partial area overlaps with the first and second partial areas. Finally, the partial first layer or partial first layer system is structured as a mask using the partial second layer or partial second layer system.
