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.
