摘要：
A process for producing a polyester film having a high strength and a high modulus of elasticity, which includes preparing a polyester resin composition comprising, adding to a polyester resin, 0.1 to 10 parts by weight, based on 100 parts by weight of the polyester resin, of an additive compound selected from the group consisting of compounds represented by the general formula (I): ##STR1## and compounds represented by the following general formula (II): ##STR2## and subjecting the resin composition to monoaxial or biaxial stretching.
