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.
