Abstract:
The present invention relates to a composition for an optical film comprising a homopolymer or a copolymer of norbonene-based monomers and a silicone resin, and to an optical film made of the same. The optical film produced by using the composition for an optical film according to the present invention can control the retardation value in the thickness direction and thus it can be useful as an optical film in variety of products.
