There is provided an aqueous resin composition excellent innsettability, flexibility, retort resistance, hygienicity, sprayability andndispersibility in water, and used to coat an internal surface of a can. Thenaqueous resin composition contains: polyester resin having a specificnstructure in a molecular chain thereof and/or at a terminal of the molecularnchain, the polyester resin having added thereto an opened ring of ancompound having a molecule with a carboxylic anhydride group therein, atnleast no less than 10% by mole of the compound being a compound having anmolecule with no less than two carboxylic anhydride groups, the polyesternresin having a resin acid value of 150 to 800 eq/10 6 g and a number-averagenmolecular weight of 5,000 to 100,000; resol-type phenol resin correspondingnto a copolymer of a formaldehyde and a phenol compound containing no lessnthan 50% by weight of a phenol compound having no less than three reactivenpoint with formaldehyde, the resol-type phenol resin having no less than onenalkoxy methyl group on average per aromatic nucleus; a basic compound;nand water, or water and an organic solvent. |
