Beschreibung
Zusammenfassung:	A water-dispersible polycondensation polyester resin having moieties of at least one polycarboxylic acid and at least one polyvalent alcohol having a terminal hydroxyl group, said polyester having a molecular weight between 300 and 3,000, a softening point between 30 DEG and 60 DEG C, said polyester additionally containing an amount of 1 to 5 mole percent based upon the moieties of polycarboxylic acid or polyvalent alcohol; moieties of an alkali metal-sulfo group containing polycarboxylic acid or polyvalent alcohol; aqueous dispersions of such water-dispersible polyester resin and the use of such water dispersions as baked upon lacquer compositions.
