Abstract: The invention concerns a process for the production of a personalised, optically variable element having polarising properties, and a film system for carrying out the process. To produce the optically variable element a film body which comprises two or more layers and which has an LCP layer comprising a liquid crystal material is applied to a substrate body which has an orientation layer for the orientation of liquid crystals. The orientation layer of the substrate body is personalised prior to application of the film body to the substrate body. The film body is then applied to the personalised orientation layer of the substrate body in such a way that the LCP layer of the film body lies on the personalised orientation layer of the substrate body for then orientation of liquid crystals of the LCP layer of the film body.

Abstract: The invention concerns a film, in particular an embossing film, a laminating film or a sticker film, and an optical security element. The film has a carrier layer and a replication layer. The film also has a layer of a liquid crystal material, which is applied to the replication layer. A diffractive structure is embossed into the surface of the replication layer, which is towards the layer of a liquid crystal material, for orientation of the liquid crystal material, said diffractive structure having at least two partial regions with different directions of orientation of the embossed structure.
