| 发明名称 | Microcapsule-type latent curing agent | ||
| 摘要 | 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. | ||

| 主权项 | 1. A microcapsule-type latent curing agent comprising: 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 the latent curing agent; wherein: the enzyme-treated gelatin film has a thickness of from 1 to 1000 nm; the enzyme-treated gelatin film is formed of a gelatin obtained by subjecting a gelatin which exhibits a jelly strength according to JIS K6503-2001 of 10 to 200 to an enzyme treatment; and the enzyme-treated gelatin film has surface irregularities that were formed by the enzyme treatment. | ||
