<p>PROBLEM TO BE SOLVED: To provide a method for producing a photocurable resin composition dispersed in an aqueous medium which can be used for curing by active energy of ultraviolet rays or the like and has efficient photocurability and excellent liquid stability.SOLUTION: In a method for producing a photocurable resin composition dispersed in an aqueous medium, the photocurable resin composition is obtained by dissolving a photoinitiator, which is solid at 30°C and 1 atm, in an ethylenically unsaturated monomer and then mixing a polyfunctional compound containing two or more ethylenically unsaturated groups in one molecule with a polymer polymerized using a heat polymerization initiator. In the photocurable resin composition method, the polymer has a partial structure derived from an ethylenically unsaturated monomer containing carboxyl groups, and after the carboxyl groups are neutralized with a base, the polymer is dispersed in an aqueous medium. In the photocurable resin composition method, a compound having an ethylenically unsaturated group is subjected to addition reaction with the polymer.</p> |
