実験手順
A solution of 95 parts by weight of lauryl methacrylate in 200 parts by weight of IP Solvent 1620 (produced by Idemitsu Petrochemical Co., Ltd.) is prepared. Argon gas is blown into the solution for 10 minutes to displace the gas entrained in the entire reaction system with argon gas. Then, benzoyl peroxide is added as a polymerization initiator in an amount of 1 mol % based on the amount of the lauryl methacrylate to the reaction system and the reaction system is kept at a temperature of 80° C. for four hours to induce polymerization of the monomer in the reaction system. Thereafter, the reaction system is cooled to 30° C. and made to add 5 parts by weight of N-vinyl-2-pyrrolidone and further add azobis-isobutyronitrile in an amount of 1 mol % based on the N-vinyl-2-pyrrolidone. The reaction system is heated to and retained at 90° C. for four hours to complete the polymerization. The lauryl methacrylate/N-vinyl-2-pyrrolidone copolymer consequently obtained in the form of a solution is labeled as "disperse charge resin A."
