Abstract:
A method for producing a security element (55) and a security element (55) in the form of a multilayered film body having a top side facing the observer. The security element (55) has a volume hologram layer, in which a volume hologram is recorded, which provides a first optically variable information item. The security element (55) has a replication layer, in the surface of which a relief structure providing a second optically variable information item is molded and which is arranged above the volume hologram layer. A partial metallic layer is arranged between the volume hologram layer and the replication layer, wherein the metallic layer is provided in one or a plurality of first zones of the security element and the metallic layer is not provided in one or a plurality of second zones of the security element.
