PURPOSE:To produce at high yield and industrially advantageously tageously a large microcapsules contg. hydrophobic liquid as a core material by using an interfacial polymerization reaction. CONSTITUTION:In a production of microcapsules in which hydrophobic liquid is covered with polyurethane or polyurethane resin by the interfacial polymn. reaction, the hydrophobic liquid formed by being dissolved with a polybasic halide and a polyvalent isocianate is added to an aq. solution of a water soluble high molecular material having OH group, NH2 group or NH group and is dispersed and then, after alkali compd. is added, a polyvalent amine or polyhydric alcohol is added. |
