[Object] To provide an aromatic polycarbonate resin composition suitable for a sunglass lens having excellent ultraviolet absorbing ability, transparency and chemical resistance, and also excellent impact resistance, heat stability and color tone stability. (A) 80 to 99.9 parts by weight of an aromatic polycarbonate resin having a viscosity average molecular weight of 20,000 to 50,000, at least two kinds of dicarboxylic acids and a diol component, and a dicarboxylic acid. With respect to a total of 100 parts by weight of 0.1 to 20 parts by weight of a copolymerized polyester resin in which 2 to 10 mol% of the component is a naphthalenedicarboxylic acid component, (B) 0.1 to 1 part by weight of a benzotriazole-based ultraviolet absorber having a maximum absorption wavelength of 350 nm or more, (C) a benzofurano-2-one type compound 0.003 to 1 part by weight, (D) 0.01 to 2 parts by weight of a phosphite stabilizer and (e) 0.01 to 2 parts by weight of a phenolic antioxidant.
