Abstract

PURPOSE:To prepare a microcapsule with improved film physical properties by a method wherein a hydrophobic liquid is dispersed in an aqueous solution containing an emulsifier and, thereafter, a compound having active hydrogen is added to form the first film and, thereafter, the second film is formed by heating under an acidic condition. CONSTITUTION:A hydrophobic liquid in which a multivalent isocyanate or a prepolymer thereof is added is dispersed or emulsified in an aqueous solution containing an emulsifier. Thereafter, a compound having active hydrogen is added and the first insoluble film is formed by heating on a surface of a fine particle. Subsequently, by heating under an acidic condition, the second insoluble film comprising an amino resin is further formed on said first insoluble film. Thus obtained microcapsule has a physically and chemically stable film and a wide application range.
