Abstract
A component has a substrate () made of a transparent material, for example glass. On this layer (), there is a linear polarizer () on which there is a layer () of a photo-oriented polymer network (PPN)(-LPP) which is oriented in locally varying fashion via its surface which covers the substrate. The layer () is adjoined by an anisotropic layer () of cross-linked liquid-crystal monomers. This layer () then has a molecular arrangement whose orientation is defined by the underlying orientation layer (). The layer () will have been photocross-linked by exposure to a suitable wavelength of light, with the result that the molecular orientation defined by the PPN layer () is fixed. The clement, denoted as a whole by 7, can then be used as an optical component which is protected against forgery, it being possible for the orientation pattern of the liquid-crystal layer or the optical information stored therein to be made visible by means of an external polarizer (), for example.
