Document Type and Number:
WIPO Patent Application WO/2018/074513
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide an optical film which contains a hydrogenated norbornene resin, while having improved lubricity without causing an increase of haze. An optical film according to the present invention contains: a hydrogenated norbornene resin which is composed of a hydrogenated product of a ring-opened polymer of a norbornene monomer having a polar group or a hydrogenated product of a ring-opened copolymer of a norbornene monomer and another copolymerizable monomer (provided that at least one of the norbornene monomer and the copolymerizable monomer has a polar group); silica fine particles; a polycondensate ester 1 of an aromatic dicarboxylic acid and an aliphatic diol, wherein OH groups at both ends of the polycondensate ester are blocked by aromatic monocarboxylic acids; and a polycondensate ester 3 of an aliphatic dicarboxylic acid and an aliphatic diol, wherein OH groups at both ends of the polycondensate ester are not blocked.
