20080259416 | Optically Variable Elements Comprising An Electrically Active Layer - There is described a security element having at least one optically variable device, in which at least one layer of the optically variable device is in the form of an electrically active layer ( | 10-23-2008 |
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 |
20090072526 | Diffractive Security Element with Individualized Code - Described is a security element for increasing the forgery-proof nature of a security document, in particular an identity card or pass, a passport or an identification card. The security element ( | 03-19-2009 |
20090162756 | Multi-Layer Body With Volume Hologram - Described is a process for the production of a multi-layer body having a volume hologram with at least two different items of image information, wherein a photosensitive layer ( | 06-25-2009 |
20100119780 | Body with a Surface Structure Which Enhances the Friction Behavior - Described is a body, comprising an elastomeric material or having an outer elastomeric layer, wherein a surface structure which enhances the friction behavior is formed into the surface of the elastomeric body or into the outer elastomeric layer of the body. The surface structure ( | 05-13-2010 |

20110128600 | OPTICAL SECURITY ELEMENT - The invention concerns an optical security element and a process for the production of an optical security element in the form of a multilayer body having a projection element ( | 06-02-2011 |
20120038988 | Multi-layer body and process for the production of a multi-layer body - A multi-layer body having a partially shaped first layer and a diffractive first relief structure shaped in a first region of a replication layer. The first layer is applied to the replication layer in the first region and, in a second region, a photosensitive layer is applied to the first layer or a photosensitive washing mask is applied thereto as a replication layer. The photosensitive layer or the washing mask is exposed through the first layer so that the photosensitive layer or washing mask is exposed differently due to the first relief structure in the first and in the second regions, and the first layer is removed using the exposed photosensitive layer or washing mask as a mask layer in the first region but not in the second region or in the second region but not in the first region. | 02-16-2012 |
