发明名称 SECURITY ELEMENT HAVING MANY OPTICALLY VARIABLE STRUCTURES
摘要 A security element includes an optically variable structure having a multiplicity of first embossed structures each including at least two flanks which converge at at least one certain angle. In at least one first partial region of the optically variable structure, at least one flank of the first embossed structures respectively has at least one additional embossed structure which is mounted on the flank of the first embossed structures or inserted into the flank of the first embossed structures. The geometry of the at least one additional embossed structure is executed to be at least near-inverse to the geometry of that flank of the first embossed structure on which the at least one additional embossed structure is mounted or inserted.
