PURPOSE: To produce epoxy resin particles having remarkably improved heat- resistance and solvent resistance, by adding a water-soluble amine hardener to an epoxy compound emulsion, and heat-treating the hardened particles.

CONSTITUTION: A water-soluble amine hardener is added to an epoxy compound emulsion, and the hardened spherical epoxy resin particles are heat-treated at ≥40°C, preferably ≥50°C. The epoxy compound is the one having ≥2 epoxy groups in one molecule, e.g. bisphenol A etherified with glycidyl group at both terminals. It can be emulsified by adding 4W30wt% surfactant having an HLB value of ≤10, based on the uncured resin. The amine hardener is piperazine, hydrazine, etc., and the amount is preferably ≤4 equivalent based on the epoxy value of the emulsion.
