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.
A security element in the form of a multilayered film body having a top side facing an observer and having a volume hologram, which provides a first optically variable information item, wherein the security element has a replication layer, in the surface of which a relief structure is molded, which has a relief depth between 10 μm to 50 μm in one or a plurality of first regions and has a relief depth between 0 to 2 μm in one or a plurality of second regions, and wherein the relief structure is filled with a volume hologram material in the first regions of the replication layer, the volume hologram being recorded in said volume hologram material.
A method for producing a security element in the form of a multilayered film body having a top side facing the observer, wherein a multilayer body comprising a replication layer is provided, wherein a relief structure is molded into the surface of the replication layer, said relief structure having one or a plurality of first regions having a relief depth of the relief structure between 10 μm to 50 μm and one or a plurality of second regions having a relief depth of the relief structure between 0 to 2 μm, wherein the first regions of the replication layer are filled with a volume hologram material, and wherein the volume hologram material is exposed for the purpose of recording a volume hologram.
