20080206688 | PHOTOTHERMOGRAPHIC MATERIALS INCORPORATING ANTIFOGGANTS - Incorporation of certain compounds into photothermographic materials provides materials with reduced initial image D | 08-28-2008 |
20100265584 | RETROREFLECTING OPTICAL CONSTRUCTION - Retroreflecting optical constructions are disclosed. A disclosed retroreflecting optical construction includes a retroreflecting layer that has a retroreflecting structured major surface, and an optical film that is disposed on the retroreflecting structured major surface of the retroreflecting layer. The optical film has an optical haze that is not less than about 30%. Substantial portions of each two neighboring major surfaces in the retroreflecting optical construction are in physical contact with each other. | 10-21-2010 |
20120039089 | OPTICAL CONSTRUCTION AND DISPLAY SYSTEM INCORPORATING SAME - Optical constructions are disclosed. A disclosed optical construction includes a reflective polarizer layer, and an optical film that is disposed on the reflective polarizer layer. The optical film has an optical haze that is not less than about 50%. Substantial portions of each two neighboring major surfaces in the optical construction are in physical contact with each other. The optical construction has an axial luminance gain that is not less than about 1.2. | 02-16-2012 |
20140197625 | LASER-PERSONALIZABLE SECURITY ARTICLES - Laser-personalizable security articles include multi-layer security documents. The multi-layer security document includes an optically transparent cover layer, a composite image and an imagable layer adjacent to the cover layer. The first surface of the cover layer is at least partially a microstructured surface, where the microstructured surface forms microlenses or a lenticular surface. The composite image is made by a collection of complete or partial images viewed through the microstructured surface of the cover layer. The composite image is located on or within the second surface of the cover layer. The imagable layer is a laser imagable layer. When imaged, a personalized second composite three dimensional image is created on or in the imagable layer. | 07-17-2014 |
20140265295 | FLEXIBLE HINGE MATERIAL COMPRISING CROSS-LINKED POLYURETHANE MATERIAL - An article may include a biodata page defining a perimeter including an edge and a hinge layer attached to at least a portion of the biodata page. The hinge layer comprises a cross-linked polyurethane. In some examples, the hinge layer may include a cross-linked thermoset polyurethane. | 09-18-2014 |
20140265301 | SECURITY FEATURE UTLIZING HINGE MATERIAL AND BIODATA PAGE - An article may include a flexible hinge comprising a first optical feature. The article also may include a biodata page comprising a second optical feature. The flexible hinge may be attached to a surface of the biodata page, and the second optical feature is substantially aligned with the first optical feature. The combination of the first optical feature and the second optical feature provides an optical effect, which may be destroyed or damaged if the flexible hinge is moved relative to the biodata page, e.g., if the flexible hinge is separated from the biodata page. | 09-18-2014 |
20150049384 | RETROREFLECTING OPTICAL CONSTRUCTION - Retroreflecting optical constructions are disclosed. A disclosed retroreflecting optical construction includes a retroreflecting layer that has a retroreflecting structured major surface, and an optical film that is disposed on the retroreflecting structured major surface of the retroreflecting layer. The optical film has an optical haze that is not less than about 30%. Substantial portions of each two neighboring major surfaces in the retroreflecting optical construction are in physical contact with each other. | 02-19-2015 |
20150053341 | PROCESSING TAPES FOR PREPARING LAMINATE ARTICLES - Processing tapes have special properties to permit them to be used to prepare laminate articles, such as security articles. The processing tapes include a backing, a pressure sensitive adhesive layer and a release surface covering the pressure sensitive adhesive layer. The backing is a dimensionally stable transparent polymeric film, and the surface on which the pressure sensitive is coated may be a treated surface. The pressure sensitive adhesive is a transparent pressure sensitive adhesive that includes a crosslinked (meth)acrylate-based polymer and has a refractive index in the range of 1.45-1.55. The (meth)acrylate-based polymer includes alkyl (meth)acrylate monomers and may include acidic monomers. | 02-26-2015 |
