Abstract
The present invention relates to a transparent resin composition which comprises (a) a (meth)acrylate based resin comprising one or more (meth)acrylate based derivatives; and (b) an aromatic based resin having a chain having the hydroxy group containing portion and an aromatic moiety.
Claims12
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.
