An organic polymer/fine inorganic particle aqueous dispersion with excellent dispersion stability which comprises a water-soluble or water-dispersible, carboxylated synthetic polymer (A) and sparingly water-soluble fine inorganic particles (B) which have been synthesized by reacting (a) a compound of an element in Group 2 of the Periodic Table with (b) at least one compound selected from organic acids, inorganic acids, and salts thereof in the presence of the polymer (A) and which have a particle diameter of 500 nm or smaller, the (A)/(B) ratio being from 10/90 to 99.99/0.01 (by weight). It is usable as a chemical for papermaking, chemical for ink-jet recording, medical material, and cosmetic material. |
