PROBLEM TO BE SOLVED: To provide a resin composition which reduces the generation of spotty and streaky defects of external appearance and the generation of discoloration and fading and, simultaneously, has excellent heat resistance, good fabricability and the like and is suited in obtaining molded articles especially for optical use, a film composed of the resin composition, and a molding method using the resin composition. SOLUTION: The resin composition comprises 100 pts.wt. thermoplastic amorphous resin having a total-ray transmittance of >=88%, an absolute value of the photoelastic coefficient of <=1.0×10-11 Pa-1, a glass transition temperature of 120-200 deg.C, a saturated water absorption of 0.05-1 wt.% and, simultaneously, a water content of <0.05 wt.% and 0.01-1 pt.wt. phosphorus based antioxidant. The film is formed of the above resin composition, and the film is an optical film. The molding method comprises conducting the plastifying molding of the above resin composition before the water content of the composition reaches 0.05 wt.%.
