An object is to provide a pigment dispersion liquid for color filters having large process margin when using a production disperser, and a negative resist composition for color filters excellent in pigment dispersibility and alkali developing property and capable of forming a color filter having high luminance and high contrast. Disclosed are a pigment dispersion liquid for color filters comprising a pigment dispersing agent which is a specific block copolymer in which at least a portion of an amino group in a repeating unit form a salt with an organophosphate compound, a pigment, a sulfonic acid derivative of C.I pigment yellow 138 and a solvent, and a negative resist composition comprising said pigment dispersing agent, a pigment, a sulfonic acid derivative of C.I pigment yellow 138, an alkali soluble resin, a polyfunctional monomer, a photo initiator and a solvent. |
