20110193335 | RETROREFLECTIVE SECURITY ARTICLES - Security laminates and articles wherein the security laminate includes a first substrate having a first major surface and a second major surface; a plurality of retroreflective elements affixed along the first major surface of the substrate, the retroreflective elements including a solid spherical core comprising an outer core surface, the outer core surface providing a first interface; a first complete concentric optical interference layer having an inner surface overlying core surface and an outer surface, the outer surface of the first complete concentric optical interference layer providing a second interface; a second complete concentric optical interference having an inner surface overlying the outer surface of the first complete concentric optical interference layer and an outer surface, the outer surface of the second complete concentric optical interference layer providing a third interface; the security laminate is retroreflective. Security articles include the foregoing security laminate affixed to a major surface of a second substrate. | 08-11-2011 |
20110200789 | RETROREFLECTIVE PAVEMENT MARKINGS - Pavement markings having a substrate with a first major surface and a second major surface; and a plurality of retroreflective elements ( | 08-18-2011 |
20130154250 | PERSONALIZED SECURITY ARTICLE AND METHODS OF AUTHENTICATING A SECURITY ARTICLE AND VERIFYING A BEARER OF A SECURITY ARTICLE - Security articles and methods of personalizing security articles. Specifically, this disclosure relates to security articles that contain a security feature that is a composite image, where the composite image includes laser-personalized security information. | 06-20-2013 |
20130344298 | STATIC DISSIPATING LASER ENGRAVABLE FILM - Laser engravable films are disclosed. In one aspect, the laser engravable film of the present invention includes a monolayer film, preferably comprising polycarbonate, having a laser engraving additive and an antistatic composition mixed within the layer of polycarbonate. In another aspect, the laser engravable film of the present invention includes a first layer, preferably comprising polycarbonate, having an antistatic composition mixed within the first layer, and a second layer, preferably comprising polycarbonate, with laser engraving additives mixed within the second layer. | 12-26-2013 |
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 |
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 |
