Abstract:
The present invention relates to a resin composition for an optical film, comprising a polyarylate resin and an amino resin having a triazine structure, and to an optical film prepared by using the same. By using the resin composition for an optical film, a thickness direction retardation can be controlled, while having a negative value, during a step of fabricating the optical film, an in-plane retardation can be controlled, and the optical film can be used as a substrate of a display instead of a glass substrate without an additional retardation compensation film.
