PURPOSE:To prepare the microscapsules which consist of the particles formed uniformly from the same substance and enclose water or water-soluble substance therein by adding inorganic fine powder to an emulsion-in-oil for coexistence, and by preventing aggregation of resulting miclocapsules. CONSTITUTION:Water or a water-soluble substance to be capsuled is emulsified by a solvent in which such substance is not dissolved in the presence of inorganic fine powder. In the resulting emulsion, the monomers whose resinous component consists mainly of the monomers having alpha,beta-ethylenic unsaturated linkage are polymerized at a temperature of 40-90 deg.C, whereby a microcapsule consisting of resinous components containing the inorganic fine powder as the shell forming component can be obtained. |
