(57) 【Abstract】 PROBLEM TO BE SOLVED: For example, when a conventional pigment dispersion composition is applied to an ink for a color filter for a liquid crystal display, coating unevenness occurs during spin coating on a glass substrate, and The disadvantages of the prior art that the brightness and the contrast of the color filter become insufficient due to the insufficient light transmittance after the formation is solved. SOLUTION: In a pigment dispersion composition comprising an organic pigment, an organic solvent and a fine dispersion component, an acidic derivative of an organic pigment and a cationic comb graft polymer are blended and dispersed as a fine dispersion component in the pigment dispersion composition. |
