  • Patent number: 7405879
    Abstract: The invention concerns an optically variable element and a security product having such an optically variable element, a foil, in particular an embossing foil or a laminating foil having such an optically variable element, and a process for producing such an optically variable element. The optically variable element has a thin film layer succession with at least one spacer layer for producing color shifts by means of interference. In a first region of the thin film layer succession the spacer layer is of a different layer thickness from in a second region of the thin film layer succession. In that case the layer thicknesses of the spacer layer in the first and second regions are so selected that in the first region of the thin film layer succession a first color shift is produced by means of interference and in the second region of the thin film layer succession a second color shift which is different from the first color shift is produced.

  • Patent number: 7401550
    Abstract: The invention concerns an apparatus and a process for producing a marking on a substrate. Substrates marked in that way are applied to documents such as for example credit cards, personal identity cards or banknotes as security features to provide protection from forgery. Embodiments of those security features have diffractive or holographic structures. The production of the markings was hitherto effected by shaping from a mold. A change in the marking is possible by changing the mole, which is time-consuming. The new apparatus and the new process are intended to permit the production of individualized markings on a substrate, at a low level of apparatus expenditure.

  • Patent number: 7403651
    Abstract: A process for the production of a multi-color image is described. Preferably a transfer film is used which has a laser-sensitive layer (4). The laser-sensitive layer (4) comprises a three-component mixture. The components are coloring agents which are bleachable with laser radiation, in particular pigments, for example cyan pigment, magenta pigment and yellow pigment. With the process the procedure is such that in the individual steps only a respective one of the pigment components is bleached insofar as the laser conditions which are respectively specific to the various pigment components are set. This means that in the case of the three-component mixture only a first component is bleached by laser treatment of a given location in a first step by laser irradiation and only one other component is bleached in an optional second step and only one third component is bleached in an optional third step.

The multilayer film (15) has a multilayer transfer or laminating film comprising two or more thin layers. A mechanically load-bearing layer with preferably a high modulus of elasticity is arranged on a surface of the multilayer transfer or laminating film. A cover layer is arranged on another surface of the multilayer transfer or laminating film. The multilayer film formed in that way is now applied to a base body of the ski (1).

  • Publication number: 20080008958
    Abstract: There is described a signing film wherein provided on a background of the signing film is a decorative printing which forms a security feature and which fluoresces when viewed under UV light. So that the decorative printing which fluoresces under UV light is not to be perceived when viewing the surface of the signing film at different viewing angles in ambient light, it is proposed that the background of the signing film has at least two background layers and between them the decorative printing comprising a lacquer which contains a high-viscosity binding agent and is mixed with pigments which fluoresce under UV light, so that after the printing operation and the drying operation it is of a small layer thickness as a consequence of the high viscosity.

  • Publication number: 20070041067
    Abstract: The present invention concerns a strip for safeguarding a document, comprising a support on which there is formed in the longitudinal direction of the strip an alternation of generally metallised regions and generally transparent regions, said alternation being capable of establishing a contrast on a scale identified as global at the level of the document to be safeguarded in such a way as to constitute protection against reproduction of the documents with which the strip will be associated, characterised in that the strip also comprises optically active elements in association with the generally metallised regions and/or the generally transparent regions of the strip to produce an optical effect on a scale identified as detail at the level of the document to be safeguarded, said optical effect making it possible to constitute a recognisable sign for identifying said document. The present invention finally concerns a security document incorporating a strip as set forth hereinbefore.
