PURPOSE:To form a polymer microcapsule having an arbitrary particle diameter with good reproducibility, to perform easily aftertreatment and to disperse easily the polymer microcapsules in a vehicle of an ink or a coating material or in an org. solvent. CONSTITUTION:Fine particles are dispersed in a non-aqueous solvent and are mixed therein by heating and a liq. wherein an ethylene copolymer is dissolved by heating in advance in the non-aqueous solvent is incorporated in the dispersion and the liq. after incorporation is furthermore heated at least the dissolving temp. of the ethylene copolymer for mixing and dispersion and, thereafter, the liq. is cooled to deposit polymer microcapsules. |
