PROBLEM TO BE SOLVED: To provide a polyester resin composition wherein peelability from a calender roll, resistance to embossing heat and solvent resistance are imparted by blending a specific resin and compound in a polyester resin composition having a specific amorphous or low-crystallinity polyester resin as main ingredients. SOLUTION: The polyester resin composition is characterized in that an organic phosphotriester compound of 0.1-3 pts.wt. as a lubricant is blended with respect to a polyester resin component of 100 pts.wt. The component comprises an amorphous or low-crystallinity polyester resin of 60-95 wt.%, which is composed of a dicarboxylic acid component having terephthalic acid as a main ingredient and a diol component comprising 1,4-cyclohexane dimethanol of 15-80 mol% and ethylene glycol of 20-85 mol%, and at least one high-crystallinity polyester resin of 5-40 wt.% selected from polybutylene terephthalate resin and polyethylene terephthalate resin.
