    Abstract: 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.

    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: 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.
