Abstract: A photochromic polyurethane laminate wherein the photochromic polyurethane layer of the laminate has been crosslinked with an isocyanate-active prepolymer using a crosslinking agent. The crosslinking agent is formulated to have at least three functional groups that are reactive with functional groups of the polyurethane or of the isocyanate-active prepolymer. A method of making the photochromic polyurethane laminate includes steps of causing the crosslinking.

Abstract: A wire grid polarizer comprises parallel grids of composite wires wherein each grid includes a coating stack having at least one high refractive index material coated on an aluminum layer. The coating stack comprising at least one high refractive index material reduces the reflection of the wire grid polarizer from between 40-50% to between 5-10%. Possible candidates for the high refractive index materials include Ge, Si and alloys of these materials having refractive indices greater than 3 with extinction coefficients above 0.2.

Abstract: An ophthalmic article having a coating system which provides antireflective, easy clean and anti-fogging properties to the ophthalmic article. The coating system includes alternating layers of low refractive index and high refractive index metal oxides and a sol-gel based hydrophilic top layer formed of one or more silanes, one or more alcohols, DI water and itaconic acid. The coating system provides favorable surface energy and particle size distribution to the ophthalmic article when the sol-gel based top layer is deposited on top surface of the alternating layers of low refractive index and high refractive index metal oxides.
