To obtain an aqueous photopolymerizable resin composition improved in odor of a solvent, storage stability and coloring and excellent in curing properties, a pattern-forming property, etching resistance and release resistance of a cured product.

A method for producing the aqueous photopolymerizable resin composition comprises polymerizing an ethylenic unsaturated carboxylic acid used as an essential monomer component in the presence of a solvent composed of sec-butyl alcohol to provide a carboxyl group-containing (meth)acrylic resin and neutralizing a part of carboxyl groups of a reaction product of the resultant carboxyl group-containing (meth)acrylic resin with an alicyclic epoxy group-containing unsaturated compound with a base and adding water thereto, removing the solvent to provide a resin in which the solvent is substituted with water and adding a polymerizable vinyl monomer to the resin.
