An object of the present invention is to provide a blue pigment dispersion composition for a color filter having high contrast and high brightness and excellent heat resistance, and a blue pigment dispersion resist composition for a color filter containing the same. The blue pigment dispersion composition for a color filter of the present invention is characterized in that it contains CI Pigment Blue 15:6, CI Solvent Blue 45, a phthalocyanine derivative having a sulfonic acid group, and a polymer having a basic group. In the case of the pigment dispersant, the alkali-soluble resin, and the organic solvent, the content of the CI solvent blue 45 is 1 to 50% by mass based on 100% of the above-mentioned CI pigment blue 15:6. |
