PCT No. PCT/JP97/00458 Sec. 371 Date Oct. 21, 1997 Sec. 102(e) Date Oct. 21, 1997 PCT Filed Feb. 19, 1997 PCT Pub. No. WO97/31045 PCT Pub. Date Aug. 28, 1997A process for preparing an aqueous dispersion of a cationic fine grain gel, comprising microemulsion polymerizing (polymerizing in microemulsions) an unsaturated monomer M under the presence of a polymer P which contains 30 to 92.5% by mole of a nonionic structure unit (a) and 70 to 7.5% by mole of a quaternary ammonium group-containing structure unit (b), and which contains the specific amount of a specific structure unit (b1) having a quaternary ammonium group and a polymerizable double bond, and an aqueous dispersion of a cationic fine grain gel obtainable by the process.
