20090289246 | METHOD FOR PRODUCING AT LEAST ONE MULTILAYER BODY, AND MULTILAYER BODY - The invention concerns a process for the production of a multi-layer body, wherein the multi-layer body includes at least two functional layers on a top side of a carrier substrate, which are structured in register relationship with each other, by a procedure whereby an underside of the carrier substrate is prepared in such a way that in a first region there results a transparency for a first exposure radiation and in at least one second region there results a transparency for at least one second exposure radiation different therefrom in register relationship with the first region, the underside is successively exposed with the first and the at least one second exposure radiation and the first exposure radiation is used for structuring a first functional layer and the at least one second exposure radiation is used for structuring at least one second functional layer on the top side of the carrier substrate. | 11-26-2009 |
20090315316 | METHOD OF GENERATING A LASER MARK IN A SECURITY DOCUMENT, AND SECURITY DOCUMENT OF THIS KIND - The invention relates to a method of generating a laser marking in a security document by means of at least one laser beam, the security document having at least one laser-markable layer and also at least one reflecting layer which overlaps at least partly with the at least one laser-markable layer and has opaque regions. The at least one reflecting layer has at least one transparent region and, at least visually, is not significantly altered by the laser treatment of the laser-markable layer. | 12-24-2009 |
20090317595 | METHOD FOR PRODUCING A MULTI-LAYER BODY, AND MULTI-LAYER BODY - Described are various processes for the production of multi-layer bodies having at least one partially shaped functional layer and at least one further partially shaped layer and the multi-layer bodies produced in that way. The multi-layer body has at least one partially shaped functional layer in register relationship with at least one further partially shaped layer, which preferably supplement each other to provide a geometric, alphanumeric, pictorial, graphic or figurative colored representation. | 12-24-2009 |
20100001508 | SECURITY DOCUMENT - The invention concerns a security document comprising a translucent carrier substrate, in particular of paper and/or plastic material, and at least one security element which is applied to the carrier substrate or embedded in the carrier substrate and which presents at least one image when viewed in the transillumination mode from at least a first side of the security document and simulates a presence of at least a first watermark in the carrier substrate, wherein the security element has at least region-wise at least one layer which simulates the first watermark, wherein the at least one layer of the security element, that simulates the first watermark, imparts thereto unexpected optical effects in relation to security elements with conventional watermarks. | 01-07-2010 |
20100045024 | SECURITY ELEMENT FOR A SECURITY DOCUMENT AND PROCESS FOR THE PRODUCTION THEREOF - The invention concerns a security element for a security document comprising a structure layer and diffractive first and second relief structures, wherein the relief structures viewed parallel to the plane of the structure layer are arranged in different planes of the security element, wherein the first relief structure adjoins a partial first reflection layer and the second relief structure adjoins a partial second reflection layer, and wherein—if the first reflection layer is towards a viewer—a second item of information generated by the second relief structure is at least partially concealed and—if the second reflection layer is towards the viewer—a first item of information generated by the first relief structure is at least partially concealed, and processes for the production of such security elements and security documents formed therewith. | 02-25-2010 |
20100151207 | TRANSFER FILM - Described is a transfer film, in particular a hot embossing film, which includes a carrier film and a transfer layer portion having a structure layer, the transfer layer portion being arranged on the carrier film and being detachable from the carrier film, wherein it is provided that the carrier film has a master relief structure on its side towards the structure layer and the structure layer on its side towards the carrier film has a relief structure complementary to the master relief structure of the carrier film. There is further provided a process for the production of the transfer film and a multi-layer body formed with the structure layer. | 06-17-2010 |
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 |
20120164391 | Method for Producing at Least One Multilayer Body, and Multilayer Body - A multi-layer body includes at least two functional layers on a top side of a carrier substrate, which are structured in register relationship with each other, by a procedure whereby an underside of the carrier substrate is prepared in such a way that in a first region there results a transparency for a first exposure radiation and in at least one second region there results a transparency for at least one second exposure radiation different therefrom in register relationship with the first region, the underside is successively exposed with the first and the at least one second exposure radiation and the first exposure radiation is used for structuring a first functional layer and the at least one second exposure radiation is used for structuring at least one second functional layer on the top side of the carrier substrate. | 06-28-2012 |
