The present invention provides a polyester resin composition having excellent shrinkage rate, capable of heat shrinking at a low temperature, and capable of improving adhesion without damaging insulation in a state such as a heat shrink film, and its production Regarding the method. Such a polyester resin composition comprises a residue derived from a dicarboxylic acid containing a residue derived from an aromatic dicarboxylic acid; and a residue derived from 4- (hydroxymethyl) cyclohexylmethyl 4 ′-(hydroxymethyl) cyclohexanecarboxylate A diol-derived residue containing a residue derived from 4,4- (oxybis (methylene) bis) cyclohexanemethanol; an alkali metal compound, and an alkaline earth metal compound, The alkali metal compound and the alkaline earth metal compound may be contained in such a content that the content ratio of alkaline earth metal element / alkali metal element derived therefrom is 0.01 to 1. |
