<p>The present invention pertains to: a colored resin composition for color filters which comprises (i) a coloring material consisting of a specific acid dye containing a xanthene skeleton or a specific dye containing a triarylmethane skeleton, (ii) a binder resin consisting of a polycarboxylic acid resin having unsaturated groups which is obtained by subjecting a reaction product of (a) a specific epoxy resin with (b) a monocarboxylic acid compound having an unsaturated group to a reaction with (c) a polybasic carboxylic acid anhydride, (iii) a photo- polymerization initiator and (iv) a solvent; a cured product thereof; color filters containing the cured product; display devices equipped with the color filters; and so on. The specific acid dye containing a xanthene skeleton is, for example, a dye derived from Rhodamine B by replacing the chloride anion (Cl-) with a specific fluoroalkyl-containing anion, while the specific dye containing a triarylmethane skeleton is, for example, a dye derived from Basic Blue 7 by replacing the chloride anion (Cl-) with a specific fluoroalkyl-containing anion. The specific fluoroalkyl-containing anion is a tris(trifluoromethane- sulfonyl)methide anion, a bis(trifluoromethanesulfonyl)imide anion, a trifluoromethanesulfonate anion, or the like. The resin composition has clear color-purity characteristics, exhibits good patternability with little residue, and provides color filters which exhibit excellent light resistance, heat resistance and solvent resistance, and so on.</p> |
