PURPOSE:To form a microcapsule only by means of adding the title composition into a liq. by preparing a composition for microcapsules with emulsifiers not reacting with each other and a compd. forming a coating film by the reaction with water as the essential components. CONSTITUTION:The emulsifiers not reacting with each other, the compd. forming a coating film by the reaction with water, and a component to be microcapsuled are mixed as the essential components to prepare the composition for microcapsules. The composition and water are mixed, and agitated to produce a microcapsule. Anionic, cationic, and nonionic surfactants can be exemplified as the emulsifier. A diisocyanate, a polyisocyanate, a urethane prepolymer, etc., are exemplified as the compd. forming a coating film by the reaction with water. |
