THIN MICROSTRUCTURED OPTICAL FILMS

摘要

Presently described are optical films, such as a brightness enhancing film, having a polymerized microstruct.ured surface disposed on a preformed polymeric film wherein the film has a thickness of no greater than 3 mils about 76 microns and the polymerized microstructured surface consists of the reaction product of a substantially non-brominated polymerizable resin composition which consists of a mixture of aromatic epoxydimethacrylate oligomers or bisphenol dimethacrylate monomers with a methacrylate diluent having a low viscosity.
