초록 ▼

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.

[ What is claimed is:] [1.] 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 resin (A) comprising a carboxyl-containing polymerizable unsaturated monomer (a) and another polymerizable unsaturated monomer (b) as monomer components, the acid value of the carboxyl-containing 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, the carboxyl-containing acrylic resin (A) being prepared by stepwise polymerization in which the monomer component of the acrylic resin (A) is divided into at least two monomer portions, and the monomer portion(s) other than a first monomer portion is added starting from a second monomer portion in the presence of the first monomer portion, the amount of the carboxyl-containing polymerizable unsaturated monomer (a) in the monomer portion to be finally added being less than the combined amount of the monomer (a) in the monomer portions already added prior to the final stage.
