Abstract
An organic polymer/inorganic fine particle-dispersed aqueous solution having excellent dispersion stability comprising a water-slightly soluble inorganic fine particle (B) having a particle diameter of 500 nm or less obtained by reacting (a) a compound of a second group element in the periodic table with (b) at least one compound selected from organic acids, inorganic acids and salts thereof in the presence of a water-soluble or water-dispersible synthetic high molecular compound (A) having a carboxyl group in a proportion of (A):(B)=10:90 to 99.99:0.01 (weight ratio). The above dispersed aqueous solution can be used as a paper-making chemical, an ink jet recording chemical, medical materials and cosmetic raw materials.
