216 g of distilled water was placed in a reaction vessel, deaerated with a nitrogen gas, and heated to 60° C. in the presence of the nitrogen gas. 15.8 g of stearyltrimethylammonium chloride, 0.07 g of polyvinyl alcohol, 33.7 g of cyclohexyl methacrylate, 37.1 g of N,N-diethylaminoethyl thacrylate, and 2.0 g of divinylbenzene were added thereto. Then, 0.44 g of potassium persulfate dissolved in 9.3 ml of distilled water deaerated with a nitrogen gas, and 0.14 g of sodium hydrogensulfite dissolved in 1.5 ml of distilled water deaerated with a nitrogen gas were simultaneously added thereto, and heated for about one hour. Subsequently, the above-described potassium persulfate aqueous solution and the sodium hydrogensulfite aqueous solution were again added thereto, followed by continuing heating for about 5 hours. Then, the system was cooled to room temperature, and filtered to obtain a polymer dispersion containing 22.8 wt% solids.
