    • An aqueous coating composition comprising a carboxyl-containing reaction product neutralized and dispersed in an aqueous medium, the reaction product being produced by the esterification reaction of a carboxyl-containing acrylic resin (A) and an epoxy resin (B), the acrylic resin (A) comprising a carboxyl-containing polymerizable unsaturated monomer (A) and another polymerizable unsaturated monomer (b) as a monomer component, the acid value of the acrylic resin (A) at a higher molecular weight region with respect to its weight average molecular weight being higher by at least 80 mg KOH/g than at a lower molecular weight region, and a process for preparing said aqueous coating composition. The coating composition is capable of forming a coating film excellent in fabrication property, corrosion resistance, water resistance, flavor-retaining ability, among others. As a consequence, even a thin film of the composition is uniform in thickness and is outstanding in resistance to cratering and sagging.
