Abstract: PURPOSE: To obtain a polyester composition providing a film having uniform and fine surface, excellent wear resistance and falling resistance by adding organic particles and an organic polysiloxane to a reaction system at a specific stage of a polycondensation process. CONSTITUTION: First, terephthalic acid or its ester-forming derivative is transesterified or esterified with glycol. Then the reaction product is subjected to polycondensation reaction. At a stage in which the intrinsic viscosity in the polycondensation process does not exceed 0.2, organic particles (preferably cross-linked polymer particles having
