Beschreibung
Zusammenfassung:	PROBLEM TO BE SOLVED: To provide an aqueous resin dispersion from which a coating film can be formed in a short period of time and a cured coating film excellent in corrosion resistance can be formed. SOLUTION: The production method of an aqueous resin dispersion includes: a polymerization step of polymerizing (a) an epoxy resin, (b) a monoglycidyl compound having no oxidative polymerizable unsaturated bond, (c) a dimer acid, and (d) a polybasic acid having no oxidative polymerizable unsaturated bond to obtain an epoxy ester resin; a grafting step of subjecting the epoxy ester resin to graft polymerization with vinyl monomers containing acid group-containing vinyl monomers to form a vinyl-modified epoxy ester resin; and a resin dispersion step of adding the vinyl-modified epoxy ester resin to an aqueous medium and neutralizing the acid group to disperse the resin. The proportion of the monoglycidyl compound (b) with respect to the total amount of the epoxy resin (a) and the monoglycidyl compound (b) is from 10 to 70 mol%; and the proportion of the dimer acid (c) with respect to the total amount of the dimer acid (c) and the polybasic acid (d) is from 30 to 70 mol%.
