Abstract:
1. A polyester resin composition which is obtained by melt mixing (A) a copolyester, in an amount of 1 to 50 parts by weight, with (B) a crystalline polyester that is not identical with component (A), in an amount of 99 to 50 parts by weight, wherein the copolyester (A) comprises a hydroxy carboxylic acid unit as constituent units, in which hydroxy carboxylic acid units of 5 or less carbon atoms are contained in amounts of 60 to 98% by mol based on 100% by mol of all the constituent units in (A) and the residue units are composed of a dicarboxylic acid unit and a diol unit, wherein hydroxy carboxylic acid units of 5 or less carbon atoms are contained in amounts of 2 to 75% by mol based on 100% by mol of all the constituent units contained in the composition, wherein the copolyester (A) has a glass transition temperature of 25 to 90° C., and wherein a molar ratio S
