Abstract

There are provided a resin composition and an optical film using the same. The resin composition includes a copolymer (A) formed by polymerizing a (meth)acryloyl morpholine-based monomer (a), a maleimide-based monomer (b), and an alkyl(meth)acrylate-based monomer (c), and the optical film is manufactured using the same. The resin composition may provide a film having excellent optical properties and optical transparency, reduced haze, excellent mechanical strength, a relatively low level of thermal expansion coefficient leading to a relatively small change in a dimension, and a relatively low level of alteration in a retardation value due to external stress.
