  • Patent number: 11654709
    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: 11623465
    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: 20230057603
    Abstract: An optically variable security element is provided for protecting objects of value. The reflective area region includes two independent relief structures, which are arranged at different levels in the z-direction and form a lower-level relief structure and a higher-level relief structure. The higher-level relief structure is supplied with a first reflection-enhancing coating following the relief profile, and the lower-level relief structure is supplied with a second reflection-enhancing coating following the relief profile. The first reflection-enhancing coating is formed in the visible spectral range with a reflection and transmission in the visible spectral range, so that the higher-level relief structure shows a first optically variable effect in a first color, and the lower-level relief structure shows a second optically variable effect through the first reflection-enhancing coating, wherein the second optically variable effect shows itself in a second, different color.

  • Patent number: 11376883
    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: 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.
