PIGMENT DISPERSION COMPOSITION, METHOD FOR PREPARING PIGMENT DISPERSION COMPOSITION, COLORED POLYMERIZABLE COMPOSITION, COLOR FILTER AND METHOD FOR MANUFACTURING COLOR FILTER

摘要

PROBLEM TO BE SOLVED: To provide a pigment dispersion composition excellent in pigment dispersibility and its stability and forming a colored film excellent in contrast, and to provide a colored polymerizable composition using the pigment dispersion composition and forming a colored film excellent in contrast and reduced in surface roughness.

SOLUTION: The pigment dispersion composition comprises a diketopyrrolopyrrole pigment, 0.1-30 parts by mass of a phthalimidoalkylated diketopyrrolopyrrole based on 100 parts by mass of the diketopyrrolopyrrole pigment, 0.1-20 parts by mass of a phthalimidoalkylated quinacridone based on 100 parts by mass of the diketopyrrolopyrrole pigment, and at least one organic solvent.
