Patent number: 11654709Abstract: 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.Type: GrantFiled: July 9, 2019Date of Patent: May 23, 2023Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Kai Herrmann Scherer, Maik Rudolf Johann Scherer, Raphael Dehmel, Michael Rahm, Giselher Dorff, Andreas Rauch, Christian Fuhse, Tobias Sattler

Patent number: 11623465Abstract: 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.Type: GrantFiled: July 9, 2019Date of Patent: April 11, 2023Assignee: GIESECKE+DEVRIENT CURRENCY TECHNOLOGY GMBHInventors: Kai Hermann Scherer, Maik Rudolf Johann Scherer, Raphael Dehmel, Michael Rahm, Giselher Dorff, Andreas Rauch, Christian Fuhse, Tobias Sattler
