摘要 <P>PROBLEM TO BE SOLVED: To provide a method for producing a pigment dispersion resin that provides a pigment dispersion having good pigment dispersibility and good storage stability even in a weak solvent system, a pigment dispersion including the pigment dispersion resin, and a coating including the pigment dispersion. <P>SOLUTION: In the method for producing a pigment dispersion resin, the pigment dispersion resin is produced by polymerizing a polymerizable unsaturated monomer component in at least three divided steps using an addition-cleaving type chain transfer agent which is 2,4-diphenyl-4-methyl-1-pentene. The polymerizable unsaturated monomer component includes an adsorptive functional group-containing polymerizable unsaturated monomer (A) and an alkyl(meth)acrylate (B) having a 4C or more alkyl group. The adsorptive functional group in the monomer (A) is selected from an amino group, a quaternary ammonium base, a sulfonic acid group, a phosphate group, and a carboxy group. The content of the monomer (B) is 50 mass% or more of the total polymerizable unsaturated monomer component used in the production of the pigment dispersion resin. The pigment dispersion resin, the pigment dispersion, and the coating are also provided. <P>COPYRIGHT: (C)2011,JPO&INPIT
