  • 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.

  • Patent number: 11602949
    Abstract: 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.

  • Patent number: 11325412
    Abstract: 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.
