(57) [Problem] To provide a pigment dispersion having improved fine dispersion stability even in a non-aqueous solvent even if the pigment concentration is high. SOLUTION: In a pigment dispersion containing a pigment, a solvent, a pigment dispersant and, if necessary, a binder resin, a weight average molecular weight of 3,000 to 100,00 is used as the pigment dispersant. 0, wherein at least 5 structural units represented by the general formula (1) are contained in the graft copolymer. A graft copolymer containing an amount corresponding to mol% A pigment dispersion comprising at least 0.2 part by weight based on 00 parts by weight.
