    摘要： 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).

    摘要： The invention relates to a security element (2), in particular in the form of a multi-layer flexible film body, with a top side facing an observer and a back side facing away from the observer, as well as a method for the production thereof. The security element (2) has one or more light-emitting elements arranged in a first area (30) of the security element which radiate light when activated and in particular are formed in each case of a self-luminous, electrically operated, display element. The security element (2) has, in the first area (30), one or more transmissive diffraction structures. The one or more transmissive diffraction structures are arranged such that at least a part of the light radiated by the activated one or more light-emitting elements transmits through at least one partial area of the transmissive diffraction structures.

    摘要： The invention relates to an optically variable element as well as a method for the production thereof. In a first area the optically variable element has at least one first color region which in the event of illumination generates a color dependent on the angle of observation and/or angle of illumination. The first color region has two or more zones (41 to 47) arranged next to each other. The two or more zones arranged next to each other have in each case a width and/or length dimension of less than 300 μm. In at least one first zone (41) of the zones (41 to 47) of the first color region a thin-film interference filter (15) is provided with at least one interference layer (17). The interference layer (17) of the thin-film interference filter (15) has a first average thickness (d1) in the first zone (41). The first average thickness is chosen such that the thin-film interference filter (15) in the event of illumination at least one particular angle of observation and/or angle of illumination generates, by means of interference, a color which differs from at least one color which is generated in the event of illumination at this angle of observation and/or angle of illumination in at least one of the other zones (42 to 47) of the first color region.
