    摘要: This invention provides a copolymer having a number-average molecular weight within a range of 2,000-100,000 and a resin acid value within a range of 10-200 mgKOH/g, which is obtained by copolymerizing (a) 5-50 parts by weight of carboxyl-containing, polymerizable unsaturated macromonomer, (b) 30-70 parts by weight of at least one polymerizable unsaturated macromonomer selected from polyalkyl (meth)acrylate macromonomers and polystyrene macromonomers, and (c) 5-65 parts by weight of at least one other polymerizable unsaturated monomer which is copolymerizable with said (a) and/or (b) component; a pigment dispersion using this copolymer; and a pigment composition using this pigment dispersion.
