摘要： An optically variable security element for securing valuable articles that viewing-angle-dependently displays a motif having at least one curve depiction that, from a first viewing direction, is visible as an initial curve having two or more connected, non-collinear segments and that, when the security element is tilted about a predetermined axis, splits into the individual segments in that the segments of the initial curve move alternatingly in different directions away from the initial curve. Each of the segments has associated with it one movement segment in the form of a sub-region of an areal motif region, such that, from the first viewing direction, the segments display the initial curve having the connected segments and that, from viewing directions tilted about the predetermined axis, they display curve depictions in which, with increasing tilt angle, the segments lie alternatingly in different directions increasingly further away from the initial curve.

摘要： A value and safety document comprises a substrate having a front side and a back side. An ink layer is applied to the front or back sides of the substrate. A first motif is incorporated into the ink layer, and is combined with a second motif. The second motif is arranged on the same side of the substrate as the first motif. The second motif is configured in the form of an emboss structure comprising a plurality of raised emboss elements having areas of different orientation. The emboss structure forms the second motif having a second tilt or motion effect, by different groups of emboss elements, having different characteristic parameters, reflecting incident light in different spatial areas. The emboss elements have respectively a lateral dimension of less than 30 μm and a height of less than 10 μm. The first motif is adapted at least partially to the second motif.

摘要： A method for producing pigments having a specified contour, comprises the steps of creating a pigment layer on a starting substrate; detaching from the starting substrate; and structuring the pigment layer into a plurality of the pigments; characterized by bringing into contact the pigment layer with an intermediate substrate, wherein the pigment layer adheres at least in sections to the intermediate substrate; and separating intermediate substrate and starting substrate.

摘要： A security element for securing security papers, value documents and other data carriers, having a lenticular image that, from different viewing directions, displays at least two different appearances. The lenticular image includes a lens grid composed of a plurality of microlenses and a radiation-sensitive motif layer arranged spaced apart from the lens grid. The radiation-sensitive motif layer includes, produced by the action of radiation, a plurality of transparency regions that are each arranged in perfect register with the microlenses of the lens grid. Outside the transparency regions produced by the action of radiation, the radiation-sensitive motif layer is opaque and patterned in the form of a first motif such that, when the security element is viewed through the lens grid from a first viewing direction, the first motif is visible as the first appearance.

摘要： A method includes using a lenticular image having a lens grid composed of a plurality of microlenses and a metallic motif layer arranged spaced apart from the lens grid; the refractive effect of the microlenses defines a focal plane and the metallic motif layer being arranged substantially in the focal plane; a line width is chosen for the demetalized sub-regions to be produced in the metallic motif layer; a marking laser source having a laser wavelength λ is selected such that the resolving power D(λ) of the microlenses of the lenticular image at the selected laser wavelength λ substantially corresponds to the line width of the demetalized sub-regions to be produced; and the metallic motif layer is impinged on through the microlenses with laser radiation of the marking laser source to produce demetalized sub-regions in the metallic motif layer.

摘要： A platelet-shaped pigment with a layer construction comprises the following layers in the order, optionally a carrier substrate; a transparent embossing lacquer layer with an embossed relief structure; a reflection-increasing coating which follows the relief structure and forms a reflecting microstructure, wherein the reflecting microstructure is present in the form of a mosaic of a multiplicity of reflecting mosaic elements and the reflecting mosaic elements do not reflect the incident light in the direction of the specular reflex, regarding the plane of the platelet, but in a spatial direction deviating therefrom and respectively have a lateral dimension 1 greater than 2 μm.

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.
