Abstract
A latent curing agent formed by holding an imidazole compound in porous resin particles is produced by emulsifying an oil phase obtained by dissolving a polyfunctional isocyanate compound in an organic solvent in an amount of 1.5 to 5 times by mass the amount of polyfunctional isocyanate compound in an aqueous phase obtained by dissolving a water-soluble polypeptide and a surfactant in water, then subjecting the emulsion to interfacial polymerization, adding a proteolytic enzyme to carry out an enzyme degradation treatment, then recovering the porous resin particles, and making an imidazole compound solution permeate into the recovered porous resin particles.
