The present invention provides an aqueous pigment dispersion in which a pigment is dispersed more highly than in the prior art, and gives a film having a high color developability and a high gloss. The pigment comprises a pigment, a dispersant, water and a solvent, wherein the pigment is a pigment treated with a polymer A having an acid group, and the polymer A is a polymer of a monomer having an acid group, or an acid group. A water-based pigment dispersion, which is a polymer obtained by polymerizing a monomer having no acid with a polymerization initiator having an acid group, and the dispersant is a polymer B having an amino group.
