RESIN COMPOSITION, OPTICAL COMPENSATION FILM USING SAME, AND METHOD FOR PRODUCING OPTICAL COMPENSATION FILM

Document Type and Number:

WIPO Patent Application WO/2013/018651

Kind Code:

A1

Abstract:

Provided are: a resin composition which is suitable for optical compensation films; an optical compensation film which uses the resin composition and has excellent retardation characteristics; and a method for producing an optical compensation film. This resin composition is characterized by containing a specific cellulose resin and a specific fumaric acid diester polymer at a specific blending ratio, or alternatively characterized by containing a specific cellulose resin and a specific fumaric acid diester polymer at a specific blending ratio as a resin component and containing the resin component and an additive that has an aromatic hydrocarbon ring or the like at a specific blending ratio. An optical compensation film can be produced using the resin composition.
