20130088782 | DURABLE ANTIREFLECTIVE FILM - Antireflective films are described having a surface layer comprising a the reaction product of a polymerizable low refractive index composition comprising at least one free-radically polymerizable fluoropolymer and surface modified inorganic nanoparticles. A high refractive index layer is coupled to the low refractive index layer. In one embodiment, the high refractive index layer comprises surface modified inorganic nanoparticles dispersed in a crosslinked organic material. The antireflective film is preferably durable, exhibiting a haze of less than 1.0% after 25 wipes with steel wool using a 3.2 cm mandrel and a mass of 1000 grams. | 04-11-2013 |
20130114142 | RETROREFLECTIVE ARTICLES INCLUDING OPTICALLY ACTIVE AREAS AND OPTICALLY INACTIVE AREAS - This disclosure generally relates to retroreflective articles and methods of making such articles. | 05-09-2013 |
20130202867 | OPTICAL ELEMENT WITH A POROUS LOW REFRACTIVE INDEX LAYER HAVING A PROTECTION LAYER - An optical article includes an optical element, a low refractive index layer disposed on the optical element having an effective refractive index of 1.3 or less and a polymeric protective layer disposed on the low refractive index layer. The low refractive index layer includes a binder, a plurality of metal oxide particles dispersed in the binder, and a plurality of interconnected voids. The polymeric protective layer does not increase an effective refractive index of the optical article by greater than 10%. | 08-08-2013 |
20130208360 | LOW REFRACTIVE INDEX DIFFUSER ELEMENT HAVING INTERCONNECTED VOIDS - An optical diffuser layer includes a binder, a plurality of metal oxide particles dispersed in the binder, and a plurality of interconnected voids. A plurality of haze generating particles are dispersed in the binder. The optical diffuser layer has an effective refractive index of 1.3 or less. | 08-15-2013 |
20130215512 | WIDE BAND SEMI-SPECULAR MIRROR FILM INCORPORATING NANOVOIDED POLYMERIC LAYER - Low loss, high reflectivity wide band mirror films provide a desired mix of specular reflection and diffuse reflection or scattering to provide semi-specular reflectivity. The mirror films generally include both a specularly reflective multilayer optical film (MOF) having a wide reflection band, and a scattering layer. In some cases a low refractive index TIR layer is sandwiched between the MOF and the scattering layer. In other cases the scattering layer contacts the MOF directly. In embodiments that include the TIR layer, the TIR layer preferably has a nanovoided morphology and includes a plurality of particles and a polymer binder. In embodiments wherein the scattering layer contacts the MOF directly, the scattering layer preferably also has a nanovoided morphology and includes a plurality of particles and a polymer binder. | 08-22-2013 |
20130222911 | OPTICALLY DIFFUSE LOW REFRACTIVE INDEX ELEMENT - An optical article includes an optical element and a low refractive index layer disposed on the optical element. The low refractive index layer having an effective refractive index of 1.3 or less and including a binder, a plurality of metal oxide particles dispersed in the binder and a plurality of interconnected voids. The low refractive index layer has a haze value of at least 30%. | 08-29-2013 |
20130261280 | PERFLUOROPOLYETHER URETHANE ADDITIVES HAVING (METH)ACRYL GROUPS AND HARD COATS - Fluorocarbon- and urethane-(meth)acryl-containing additives and hardcoats. The hardcoats are particularly useful as a surface layer on an optical device. | 10-03-2013 |
20140221689 | PERFLUOROPOLYETHER URETHANE ADDITIVES HAVING (METH)ACRYL GROUPS AND HARD COATS - Fluorocarbon- and urethane-(meth)acryl-containing additives and hardcoats. The hardcoats are particularly useful as a surface layer on an optical device. | 08-07-2014 |
