    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.

    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.

The security element comprises at least one luminous layer (2) that can emit light (20), and at least one mask layer (4) that, when the security element (1) is viewed from the viewing side, is arranged in front of the at least one luminous layer (2). 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) has a substantially higher transmittance than the at least one opaque region (5) in respect of light (20) emitted by the at least one luminous layer (2), preferably a transmittance that is at least 20% higher, particularly preferably a transmittance that is at least 50% higher.

    Abstract: Methods for producing a multilayer body (1), and a multilayer body (1). The method for producing a multilayer body includes: —providing a carrier layer (10); —applying a first replication varnish layer (11) to the carrier layer (10); —molding a plurality of microlenses (12) arranged in the form of a grid into the first replication varnish layer (11a); —applying at least one layer (14) to be structured to the side of the carrier layer (10) opposite the plurality of microlenses; —structuring the at least one layer (14) to be structured using a separate high-resolution mask (23) such that a plurality of microimages (15) arranged in the form of a grid are formed by removal in areas of the at least one layer (14) to be structured. A multilayer body (1) has a carrier layer (10) and a first replication varnish layer (11a), applied to the carrier layer (10), into which a plurality of microlenses (12) arranged in the form of a grid are molded, and with a plurality of microimages (15) arranged in the form of a grid arranged on the side of the carrier layer (10) opposite the plurality of microlenses (12) arranged in the form of a grid.

    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).
