SOLUTION: The diol component which constitutes the copolymer polyester resin is desirably ethylene glycol or cyclohexane dimethanol. The dicarboxylic acid component is desirably terephthalic acid or isophthalic acid. When the diol component comprises ethylene glycol and cyclohexane dimethanol, the molar ratio is desirably (199)/(99-1). Its relative viscosity being an index of a degree of polymerization is 0.5-1.2. The polycarbonate mixed has a molecular weight of 15,000-30,000. 100 pts.wt. resin composition comprising 10-900 pts.wt. polycarbonate resin and 100 pts.wt. copolymer polyester resin is mixed with 0.01-1 pt.wt. 10-30C fatty acid such as stearic acid.
