The polyester resin (A) is a diol unit containing a dicarboxylic acid unit and a diol unit, and 1 to 60 mol% of the diol unit has a cyclic acetal skeleton, and has an average particle size of 1 μm or less. The polyester resin composition containing 0.5-30 mass% of core-shell type rubbers whose absolute value difference of refractive index is 0.02 or less with respect to the refractive index of the said polyester resin (A). |
