<p>A pigment dispersion composition for color filters which comprises a coloring agent, a resin, and an organic solvent that can dissolve the resin, characterized by containing, as the coloring agent, a modified pigment (D) that comprises a pigment (A), and a modified polyamine (B) and a polymer (P) which are present on the surface of the pigment (A); and color filters. The modified polyamine (B) is a product obtained by reacting a vinyl copolymer (B-1) with amino groups of a polyamine, said vinyl copolymer (B-1) having, at one terminal, a functional group that can react with an amino group and thereby form an amide linkage. The polymer (P) is a polymer prepared by polymerizing at least one polymerizable unsaturated monomer (C) that is soluble in a non-aqueous solvent and that forms a polymer insoluble or slightly soluble in a non-aqueous solvent. Thus, color filters which exhibit excellent dispersion stability and contrast can be produced using a general-purpose pigment.</p> |
