PROBLEM TO BE SOLVED: To provide a red pigment dispersion resist composition for a color filter which is excellent is dispersion stability, tinctorial strength, contrast, brightness, heat resistance, and solvent resistance.SOLUTION: A red pigment dispersion resist composition for a color filter contains C.I.Pigment Red 221 and C.I.Pigment Red 177, a pigment dispersion aid represented by general formula (1) and/or (2), an alkali-soluble resin, a photopolymerizable compound, a photopolymerization initiator, and an organic solvent. In general formulae (1) and (2), X and Y are the same or different, and represent a phenyl group which may be substituted with F, Cl, Br, NO, CHor OCH; M represents H, Na, K, NHor NRRRR(R, R, Rand Rare the same or different, and represent saturated or unsaturated aliphatic hydrocarbon groups which may be substituted with other substituents and have 1 to 10 carbon atoms or represent aromatic hydrocarbon groups which may be substituted with other substituents and have 6 to 10 carbon atoms); and m is an integer of 1 or more.SELECTED DRAWING: None |
