ABSTRACT:
A process for producing a microparticulate hardening catalyst, comprising the steps of jetting a liquid composition containing epoxy resin hardening catalyst (A), monomer having an ethylenically unsaturated group (B) and photopolymerization initiator (C) through a minute nozzle into a gas so as to form microparticles; and while the microparticles are floating, irradiating the same with high-energy rays to thereby effect polymerization of the monomer having an ethylenically unsaturated group (B).
