Abstract:
(EN) The present invention relates to an optical film for polarizer protection, and a polarizing plate and an image display device comprising the same, the optical film for polarizer protection being capable of effectively inhibiting the generation of an interference pattern which is derived from a polyester-based base film and exhibiting low curl properties, thereby being appropriately applied as a polarizer protection film, etc. The optical film for polarizer protection comprises: a polyester-based base film having a refractive index of 1.6 to 1.7; and a hard coating layer which is formed on the base film, has a refractive index of 1.53 to 1.6, and has a thickness of 13 to 25 μm, wherein the hard coating layer comprises a predetermined cross-linked copolymer.
(FR) La présente invention concerne un film optique pour la protection d'un polariseur, ainsi qu'une plaque de polarisation et un dispositif d'affichage d'images comprenant ledit film, le film optique pour la protection de polariseur étant capable d'inhiber efficacement la génération d'un motif d'interférence qui est dérivé d'un film de base à base de polyester et présentant de faibles propriétés de gondolage, étant ainsi appliquée de manière appropriée en tant que film de protection de polariseur, etc. Le film optique pour la protection de polariseur comprend : un film de base à base de polyester ayant un indice de réfraction de 1,6 à 1,7; et une couche de revêtement dur qui est formée sur le film de base, a un indice de réfraction de 1,53 à 1,6, et a une épaisseur de 13 à 25 µm, la couche de revêtement dur comprenant un copolymère réticulé prédéterminé.
(KO) 본 발명은 폴리에스테르계 기재 필름에서 유래하는 간섭 무늬의 발생을 효과적으로 억제할 수 있고, 낮은 컬 특성을 나타내어, 편광자 보호 필름 등으로 적절히 적용될 수 있는 편광자 보호용 광학 필름과, 이를 포함하는 편광판 및 화상 표시 장치에 관한 것이다. 상기 편광자 보호용 광학 필름은 1.6 내지 1.7 의 굴절율을 갖는 폴리에스테르계 기재 필름; 상기 기재 필름 상에 형성되어 있고, 1.53 내지 1.6 의 굴절율을 가지며, 13 내지 25 μm의 두께를 갖는 하드코팅층을 포함하고, 상기 하드코팅층은 소정의 가교 공중합체를 포함하는 것이다.
