Abstract: A reflective polarizer suitable for use in a display device is disclosed herein. The reflective polarizer comprises: a multilayer optical film comprising alternating layers of first and second polymeric layers that reflects light of a first polarization state and transmits light of a second polarization state, wherein for normally incident light of the second polarization state, the reflective polarizer has an internal percent transmission of at least 95% at 410 nm, and at most 25% at 380 nm. Also disclosed herein is a display device comprising the reflector polarizer.

Abstract: Presently described are optical films, such as a brightness enhancing film, having a polymerized microstructured surface disposed on a preformed polymeric film wherein the film has a thickness of no greater than 3 mils and the polymerized microstructured surface consists of the reaction product of a substantially non-brominated polymerizable resin composition.

Abstract: Optical films having a polymerized microstructured surface are described. The polymerized microstructured surface comprises the reaction product of a polymerizable resin composition comprising 10% to 100 wt-% of at least one biphenyl di(meth)acrylate monomer. The di(meth)acrylate monomer comprises a core biphenyl structure having two aromatic rings connected with a C—C bond. The biphenyl di(meth)acrylate monomer preferably comprises a sufficient amount of ortho and/or meta(meth)acrylate substituents such that the monomer is a liquid at 25° C.

Abstract: Nanocomposite hardcoats having smudge and abrasion resistant properties are disclosed. Latent reactive nanoparticles are contained within a binder phase to form a nanocomposite. When deprotected and treated with a reactive fluorochemical, nanoparticles present at the surface of the nanocomposite become permanently modified and impart smudge resistance. The nanocomposite hardcoats may optionally be supported on a primary substrate.
