Abstract

The present invention provides a resin which is low in birefringence and superior in transparency, mechanical strength and dimension stability, and has high heat resistance and good fluidity, and which can be suitably used for optical materials. A resin composition obtained by blending a polyester polymer obtainable from a dicarboxylic acid compound and a dihydroxyl compound with a polycarbonate, wherein the dicarboxylic acid compound comprises an alicyclic dicarboxylic acid and/or an ester-forming derivative thereof, and the polyester polymer comprises fluorine dihydroxyl compounds. The present invention can provide a material which is low in birefringence and superior in transparency, mechanical strength and dimension stability, and has high heat resistance, good fluidity, and good balance between moldability and optical properties, and can provide a resin which can be suitably used for optical materials such as a camera lens, an eyeglass lens, an optical disk, an optical fiber and an optical sheet.
