POLYESTER RESIN COMPOSITION

摘要

A polyester resin composition containing 70 to 99.5% by mass of a polyester resin (A) which contains a dicarboxylic acid unit and a diol unit and in which 1 to 60 mol % of the diol unit is a diol unit having a cyclic acetal skeleton, and 0.5 to 30% by mass of a core/shell type rubber which has an average particle size of 1 μm or less and which exhibits an absolute difference between the refractive index thereof and the refractive index of the polyester resin (A) is 0.02 or less.
