사전 형성된 중합체 필름 상에 배치된 중합된 미세구조화 표면을 갖는 광학 필름, 예를 들어, 휘도 향상 필름이 이제 설명되며, 상기 중합체 필름은 두께가 약 76 마이크로미터 (3 mil) 이하이고 상기 중합된 미세구조화 표면은 방향족 에폭시 다이메타크릴레이트 올리고머 또는 비스페놀 다이메타크릴레이트 단량체와 점도가 낮은 메타크릴레이트 희석제의 혼합물로 이루어지는 실질적으로 브롬화되지 않은 중합성 수지 조성물의 반응 생성물로 이루어진다. 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.
