Abstract: The invention relates to a depiction arrangement for security papers, value documents, electronic display devices or other data carriers, having a grid image arrangement for depicting a target image (40) that is broken down into two or more partial target images (42, 44), having a motif image that is subdivided into a plurality of periodically or at least locally periodically arranged cells (24) in each of which are arranged mapped regions of one or more of the partial target images (42, 44), a viewing grid (22), composed of a plurality of viewing grid elements, that, when the motif image is viewed, reconstructs the complete target image (40) from the mapped regions arranged in the cells (24), the motif image being, independently of the cell subdivision, split into at least first and second microinformation regions (60, 62) in which the cells each include different combinations of mapped regions of the partial target images (40, 42), and the microinformation regions (60, 62) being arranged in the shape of specified image motifs that exhibit information-bearing image patterns whose dimensions are below the resolution limit of the human eye.

Abstract: A platelet-shaped magnetic effect pigment is provided for use in a printing ink, and includes a layer construction with a magnetic layer and at least one optical functional layer, such that the magnetic layer is based on a magnetic material having a column-shaped nanostructure and the magnetic columns respectively have a largely uniform preferential magnetic direction deviating from the platelet plane.

Abstract: A composite glass comprises two glass and/or plastic plates and an intermediate foil arranged between the glass and/or plastic plates. The composite glass, due to the intermediate foil, is configured differently in a side-dependent manner, by appearing to a viewer more transparent from an inner side than from an outer side. The composite glass, due to the intermediate foil, appears to the viewer different in a viewing angle-dependent manner from the outer side.

Abstract: A security element (1) for a security paper, value document or the like, having a carrier (8) which has an areal region (3) which is divided into a multiplicity of pixels (4) which respectively includes at least one optically active facet (5), whereby the majority of the pixels (4) respectively have several of the optically active facets (5) of identical orientation per pixel (4), and the facets (5) are so oriented that the areal region (3) is perceptible to a viewer as an area that protrudes and/or recedes relative to its actual spatial form.

Abstract: An optically variable security element has a multicolored, reflective areal region including a first relief structure disposed at a higher level than a second relief structure. The first relief structure has a first ink coating and the second relief structure has a second, different ink coating. The two relief structures overlap in an overlap region. The first ink coating of the first relief structure is disposed at a higher level in the overlap region and has at least one recess the dimension of which is more than 140 μm. The first ink coating comprises an edge region adjoining the recess, and as a bicolor register feature the first relief structure lets the edge region of the first ink coating appear with a first color impression and the second relief structure through the recess lets the second ink coating appear with a second, different color impression in mutual register.

Abstract: An optically variable security element wherein the areal expansion whereof defines a z direction standing perpendicularly thereon, and has a multicolored, reflective areal region. The areal region includes two relief structures arranged at different height levels in the z direction. The relief structures are each supplied with an ink coating which produce a different color impression. The ink coating of the relief structure disposed at a higher level is configured in the feature region as a regular or irregular grid with grid elements and grid spaces. The dimensions of the grid elements and/or grid spaces are below 140 μm at least in one direction, so that, in the feature region, for a viewer from at least one viewing angle, the ink coating of the relief structure disposed at a lower level is visible through the grid spaces of the ink coating of the relief structure disposed at a higher level.
