    • PROBLEM TO BE SOLVED: To provide a method for producing a water-dispersed slurry coating excellent in storage stability with coating resin particles prevented from mutual aggregation, and also excellent in the surface smoothness of the resulting coating film after baking curing. SOLUTION: The method for producing the water-dispersed slurry coating comprises the following procedure: An aqueous dispersion(G) with particles(A) dispersed in an aqueous medium(F) is admixed with a resin(b) or a solution(c) with the resin(b) dissolved in a solvent(y), thus forming particles of the resin(b) or the solution(c), wherein, if the resin(b) is dissolved in the solvent(y), also removing the solvent(y), thereby obtaining an aqueous dispersion(X) as the objective slurry coating where resin particles(B) having volume-average size larger than that of the particles(A) and comprising the resin(b) are dispersed in the aqueous medium(F).
