Abstract: A method for manufacturing the security element transfer material, a method for the register-accurate transfer of security elements from the security element transfer material to a value document substrate, and a value document which was equipped with a security element while employing the security element transfer material, wherein the security element transfer material has a temporary carrier material and a plurality of security elements and a plurality of register mark elements which are arranged on a main area of the temporary carrier material and have a layered composite structure. Each register mark element represents a register mark or contains a register mark, and each register mark is assigned to at least one security element. Apart from the security elements and the register mark elements, the temporary carrier material is free from layered composite material.

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 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.

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 μm 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.
