Abstract of the Disclosure Disclosed is an aqueous coating resin composition to be applied to a metal substrate, particularly an inner surface of a metal can or can closure on which an undercoating layer is formed. This coating composition comprises an aqueous dispersion of a carboxyl group-excessive epoxy resin-acrylic resin partial reaction product in the presence of ammonia or an amine in an amount sufficient to maintain the pH value of the composition between 5 and 11, said carboxyl group-excessive epoxy resin-acrylic resin partial reaction product being formed by reacting (a) an alkali- neutralizable acrylic resin having a number average mole- cular weight of from 5,000 to 100,000, which is obtained by copolymerizing 12 to 50 % by weight of acrylic acid or methacrylic acid with 50 to 88 % by weight of at least one member selected from the group consisting of styrene, methylstyrene, vinyltoluene and alkyl esters of acrylic acid and methacrylic acid having 1 to 8 carbon atoms in the alkyl group, with (B) an aromatic epoxy group having 1.1 to 2,0 epoxy groups on the average in one molecule and a number average molecular weight of at least 1,400. This composition is excellent in the storage stability, and provides a coating excellent in the adhesion, processabi- lity, flavor retaining property and resistance to boiling water.
