    • An aluminum chelate-based latent curing agent having excellent latency and thermal response includes a latent curing agent in which an aluminum chelating agent is retained in a porous resin obtained by interfacial polymerization of a polyfunctional isocyanate compound, and an enzyme-treated gelatin film coating such latent curing agent. This microcapsule-type latent curing agent can be produced by dissolving an aluminum chelating agent and a polyfunctional isocyanate compound in a volatile organic solvent, charging the obtained solution into a gelatin-containing aqueous phase, carrying out interfacial polymerization by heating and stirring, and subjecting the gelatin to an enzyme treatment by adding an enzyme to the obtained polymerization reaction mixture.
    • 具有优异潜在性和热响应性的铝螯合物潜固​​化剂包括其中铝螯合剂保留在通过多官能异氰酸酯化合物的界面聚合获得的多孔树脂中的潜在性固化剂,以及经酶处理的明胶膜包衣 潜在固化剂。 这种微胶囊型潜在性固化剂可以通过将铝螯合剂和多官能异氰酸酯化合物溶解在挥发性有机溶剂中,将所得溶液装入含明胶的水相中,通过加热和搅拌进行界面聚合,并且 所述明胶通过向所得聚合反应混合物中加入酶进行酶处理。
