Abstract:
1. A process for the production of a personalised, optically variable element having polarising properties, wherein 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, that the orientation layer of the substrate body is personalised prior to application of the film body to the substrate body, and that the film body is 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 the orientation of liquid crystals of the LCP layer of the film body, wherein after the application of the film body to the personalised orientation layer the LCP layer is liquefied, oriented and solidified, wherein the orientation layer of the substrate body is personalised by partial printing on the orientation layer.
