Abstract: The present invention is to provide a resin composition capable of producing a molded product sufficiently excellent in hydrolysis resistance and mold release characteristics and having an excellent balance between heat resistance and fluidity, even if a heat stabilizer and a mold release agent are contained.
The present invention relates to a resin composition, comprising: (A) a polyarylate resin; (B) a melt-polymerized polycarbonate resin; (C) a specific phosphite compound; and (D) a dipentaerythritol fatty acid ester, a mass ratio (A/B) of the (A) polyarylate resin and the (B) melt-polymerized polycarbonate resin being from 2/98 to 98/2, and the resin composition having a Vicat softening point of 140° C. or higher.
