<p>A microencapsulated silane coupling agent includes adduct particles of an epoxy compound and an imidazole silane coupling agent, and an ethyl cellulose film coating a periphery of the adduct particles, in which the ethyl cellulose film is crosslinked by a polyfunctional isocyanate compound. Preferred examples of the imidazole silane coupling agent include a compound represented by the formula (1), wherein R1 and R2 are each independently a hydrogen atom or a lower alkyl group, and R3 is a lower alkyl group.</p> |
