摘要： A flat security element with microreflectors arranged as a microreflector pattern in a main plane of the security element. The microreflectors present a motif made up of image points to a viewer. The motif appears for the viewer as lying outside the main plane of the security element. Two of the microreflectors are adjusted in each case to produce one of the image points of the motif appearing for the viewer as lying outside the main plane. The microreflector pattern has several groups of microreflectors. Each of the groups is provided to represent to the viewer a perspective view of the motif after tilting the security element about an axis lying in the main plane. Image points of the motif are shifted by shift ranges of different sizes through the tilting.

摘要： 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.

摘要： A method for producing pigments comprises the steps of creating a first layer on a substrate, structuring the first layer and detaching the pigments from the substrate. In the present case, the first layer is a crack-forming layer, so that the first layer is structured by the arising of cracks. Prior to detaching the pigments, a pigment layer is applied onto the first layer structured by the cracks.

摘要： A method for manufacturing a value document includes: providing a value document substrate; printing the value document substrate with magnetically orientable effect pigments which are dispersed in a UV-curable lacquer; the step of exposing the lacquer containing the magnetically orientable effect pigments to a dynamic magnetic field; the step of irradiating the lacquer containing the effect pigments with UV radiation; and optionally the step of embossing the cured or at least partially cured UV lacquer.

摘要： It is disclosed a security element comprising a substantially flat substrate including first and second areas, wherein the first area displays a first motif and generates a first color movement effect to be seen in the first motif while the substrate gets tilted over a first angular tilting range, the second area displays a second motif and generates a second color effect to be seen in the second motif and within a second angular tilting range, the first and second angular tilting ranges are different, and the first area comprises either a micro-mirror structure or a print of magnetically oriented pigments and the second area comprises the other one of the micro-mirror structure and the print of magnetically oriented pigments.

摘要： 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.

摘要： 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.

摘要： A flat security element has a main plane and microreflector arranged in a microreflector pattern and present at least one motif that, when the security element is tilted, has a motif effect that relates to the main plane. The microreflector pattern causes a first and a second motif effect, wherein the first motif effect occurs during a tilting movement about a primary axis, if the security element is at the same time oriented within a first tilting angle range about a secondary axis, and the second motif effect occurs during the tilting movement about the primary axis, if the security element is at the same time oriented within a second tilting angle range about the secondary axis.

摘要： An optically variable security arrangement for securing valuable articles, comprises a first sub-element having a two-dimensional relief grid composed of a plurality of grid elements and that has, in at least one spatial direction R1, a first line screen p below 500 μm, and in which the grid elements are each formed from at least two relief elements that are directionally reflective in different directions, and a second sub-element having at least one dot and/or line grid that, in a spatial direction R2, has a second line screen q. A movement effect is created by the interplay of the relief grid and the dot and/or line grid when the security arrangement is tilted.
