摘要： An object of the present invention is to provide cationic hollow crosslinked polymer particles that maintain a cationic property over a wide pH range, has adequate strength, and is favorable for use in filled paper, pigments for coating paper, additives for paints, fillers for resins, rubbers, and the like. Another object of the present invention is to provide a method of producing the abovementioned cationic hollow crosslinked polymer particles with excellent characteristics in a stable manner. The hollow crosslinked polymer particles of the present invention are characterized in that (I) the zeta potential as measured in an aqueous medium of pH 2 to 9 is in the range of null5 to null100 mV, (II) the volume hollowness is in the range of 1 to 80%, and (III) the average particle diameter is in the range of 0.03 to 10 nullm. This hollow crosslinked polymer particles are produced by a method that (a) 1 to 99.99 weight % of a crosslinking monomer, (b) 0.01 to 15 weight % of a cationic monomer, and (c) 0 to 98.99 weight % of a copolymerizable monomer that is non-crosslinking and nonionic (the total amount of the monomers being 100 weight %) are polymerized under the presence of polymer particles that are swellable by at least one of the above monomers. This hollow crosslinked cationic polymer particles are utilized for paint composition, cationic electrodeposition paint composition, resin composition, filled paper, paper coating composition, and coated paper, and the like.
