A pigment-dispersing agent obtained by polymerizing an addition-polymerizable monomer having an acidic functional group and other addition-polymerizable monomer in the presence of a polymerization initiator, the polymerization initiator being a diazotization product prepared by diazotizing at least one compound selected from the group consisting of an anthraquinone derivative having an aromatic amino group, an acridone derivative having an aromatic amino group and an organic dyestuff having an aromatic amino group. The above pigment-dispersing agent provides a water-based pigment dispersion which forms a water-based coating composition or water-based ink having excellent gloss, excellent clearness and high tinting strength, and the gloss, clearness and tinting strength of the water-based coating composition are comparable to those of existing oil coating compositions.
