20080280107 | Film Comprising a Polymer Layer - The invention concerns a film, in particular a stamping film, laminating film or sticker film, which has at least one anisotropic polymer layer of an at least partially oriented liquid crystal material. The anisotropic polymer layer has one or more first regions which form a first security feature and in which the anisotropic polymer layer has properties which linearly polarise or which rotate the direction of rotation, and one or more second regions which form a second security element and in which the anisotropic polymer layer has circularly polarising properties. The first security feature is visualised when viewed through a first polariser and the second security feature is visualised when viewed through a second polariser responsive to a different polarisation state from that of the first polariser. | 11-13-2008 |
20080213516 | Method For the Creation of Color Effect Images - There is described a method of producing color effect images on a carrier substrate, wherein it is provided that a latent magnetic image comprising magnetic pixels and non-magnetic pixels is produced on a magnetisable printing form, a carrier substrate with a decorative layer applied to the carrier substrate and provided with non-spherical, preferably needle-form or flake-form magnetic color effect pigments is moved past the magnetisable printing form so that color effect pigments of the decorative layer ale changed in their orientation relative to the carrier substrate by the field line image produced by the magnetic pixels of the magnetisable printing form, and the color effect pigments are fixed in the decorative layer in the orientation which is changed by the field line image of the printing form. There is further described an apparatus for carrying out the method and a multi-layer body produced therewith. | 09-04-2008 |
