Abstract

There are provided a resin composition and an optical compensation film formed using the same, and more particularly, to a resin composition comprising (a) alkyl (meth)acrylate units, (b) styrene units, (c) 3 to 6 element heterocyclic units substituted with at least one carbonyl group and (d) vinyl cyanide units, and an optical film formed using the resin composition. Further, a resin composition according to the present invention can provide an optical film having excellent optical properties and superior optical transparency, less haze and superior mechanical strength and heat resistance simultaneously. Therefore, an optical film formed using a resin composition of the present invention can be used in various applications, e.g., electronic information devices such as display devices. Particularly, the optical film is suitable for a compensation film used in the IPS mode.
