Zusammenfassung: | To provide a pigment dispersion having good viscosity stability with time and allowing formation of a pattern which is excellent in adhesiveness through development and surface roughness.SOLUTION: A pigment dispersion comprises (A) a pigment, (B) a dispersant and (C) a solvent, in which the (A) pigment contains a halogenated zinc phthalocyanine pigment, and the (B) dispersant contains a polymer having a repeating unit represented by a general formula (1): -(CHC(R)(XNRRR))-, Yand a repeating unit represented by a general formula (2): -(CHC(R)(ZNRR))-. In the polymer, a content percentage of the general formula (1) is 20 mol% or less with respect to a total of a content percentage of general formula (1) and a content percentage of the general formula (2), and the polymer has an amine value of 80 mgKOH/g or more and an acid value of less than 1 mgKOH/g. A content proportion of the (B) dispersant with respect to 100 pts.mass of the (A) pigment is 50 pts.mass or less.SELECTED DRAWING: None
