Abstract
(EN)

PROBLEM TO BE SOLVED: To provide a resin composition having heat resistance, and excellent processability and chemical resistance, and to provide an optical film using the resin composition.

SOLUTION: This resin composition includes: a component (A) of 99.9-70 wt.% acrylic resin having an acid value of 0.01-0.30 mmol/g, and a glass transition temperature of 120C; and a component (B) of 0.1-30 wt.% acrylic resin having an acid value of 0.2-5.5 mmol/g, and a glass transition temperature of 40-115C.
