  • Publication number: 20210283939
    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 ?m. 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.

  • Patent number: 11110734
    Abstract: 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.

  • Publication number: 20210268825
    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 ?m 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.

  • Publication number: 20210252900
    Abstract: 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.

  • Patent number: 10639925
    Abstract: An optically variable security element having an areal motif region provided in a depiction region with a plurality of reflective, planar facets. Each planar facet is characterized by an inclination angle against the plane of the areal motif region, which inclination angle has, as inclination components, a parallel component parallel to a target curve in a center position, and a normal component perpendicular to the target curve in the center position. For the planar facets in the depiction region, a first of the two inclination components are chosen dependent on the distance of the respective facet from the target curve, and a second of the two inclination components being chosen in a predetermined spreading range independently of the distance of the respective facet from the target curve.

The optically variable area pattern includes at least two subregions having a multiplicity of identically oriented facets. The facets of the at least two subregions differ from each other with respect to the inclination angle relative to the plane and/or the azimuth angle in the plane.
