摘要

A pigment dispersion composition includes a graft polymer having a side chain to which an unsaturated double bond is pendant, the graft polymer comprising a copolymerization component in the main chain of the graft polymer in an amount of from 5% by mass to 30% by mass, the copolymerization component comprising at least one of acrylic acid or methacrylic acid; a pigment; and an organic solvent.
