Process for obtaining oil modified polyester resins, characterized in that it consists in reacting a lower dialkyl ester of terephthalic acid, with ethylene glycol, glycerol and a fatty oil, the proportions of these components being selected in such a way that the molar ratio of the fatty oil to the total of reactants is from 0.010 to 0.04, the molar ratio of the fatty oil to the total of reactants from 0.075 to 0.25, the ratio of the hydroxyl groups of ethylene glycol and of the glycerin to the terephthalyl radicals is greater than 2., 0, and that the molar ratio of ethylene glycol to glycerin is not greater than 1.0.
