Abstract:
1. A method for manufacturing an optical film, the method comprising the steps of: preparing a resin composition comprising (a) a copolymer comprising 50 to 99% by weight of a (meth)acrylate based unit and 1 to 50% by weight of a cyclic based unit having a cyclic portion derived from N-cyclohexylmaleimide and (b) an aromatic based resin having a chain having a hydroxy group containing portion and an aromatic moiety; and shaping the optical film by using the resin composition, wherein a haze value of the optical film is 2.5% or less, the aromatic based resin includes a phenoxy based resin, and the aromatic based resin includes at least one type of 5 to 10,000 units that are represented by Formula I: wherein X is a divalent group comprising at least one benzene cycle and R is a straight- or branched-chained alkylene group having 1 to 6 carbon atoms.
