An object of the present invention is to provide a resin composition for a novel reverse wavelength dispersion film which is excellent in saponification resistance, transparency, positive birefringence and reverse wavelength dispersion, and the resin composition for a reverse wavelength dispersion film of the present invention contains a modification. a polysaccharide (A), wherein the modified polysaccharide (A) chemically modifies at least one functional group selected from the group consisting of a hydroxyl group, a carboxyl group and an amine group to be selected from the group consisting of an ether group and a urethane. At least one functional group consisting of a group consisting of a ureido group, a ureido group, a guanamine group, and an imine group, and an average molecular dispersion of all monosaccharide units constituting the modified polysaccharide (A) is 0.50 to 20.0, which is a reverse wavelength The resin composition for a dispersion film was formed into a film having a film thickness of 80 μm, and the absolute value of the reflection chromaticity b* determined in accordance with JIS-Z8729 was 0 to 1.0. |
