Pigment dispersion composition, use thereof and compound for pigment treatment

Abstract

A pigment dispersion composition which can be suitably applied in such fields as color filters, black matrices and ink jet recording where it is necessary to finely disperse pigments still with retention of good dispersion stability and temporal stability even when the total amount a pigment derivative, pigment intermediate, colorant derivative and colorant intermediate, and/or a pigment dispersant is small. Another object is a pigment dispersion-based resist composition which can give color filters high in permeability, excellent in contrast and causing no bleeding or black matrices high in light-shielding and insulating properties, and causing no bleeding. And a pigment dispersion composition which is prepared by dispersing a pigment using a pigment derivative, pigment intermediate, colorant derivative and/or colorant intermediate each having a functional group reactive with a carbodiimide group and having adsorption ability on the pigment surface, and a carbodiimide compound containing at least one carbodiimide group.
