Abstract:
1. An ink-jet ink composition for a color filter comprising an epoxy group-containing polymer (A) having a weight average molecular weight from 2,000 to 20,000 in terms of the polystyrene calibrated-weight average molecular weight and an epoxy equivalence from 140 to 1,000 g/mol which is polymerized using at least a monomer having a carbon-carbon unsaturated bond and an epoxy group; an epoxy group-containing compound (B) having two or more epoxy groups, a molecular weight from 160 to 7,000 and an epoxy equivalence from 80 to 3,500 g/mol; and a polycarboxylic acid derivative (C) in which carboxylic acid (c1) having the structure represented by the following Formula (1′) is rendered latent by vinyl ether (c2), wherein the equivalence ratio of carboxyl groups rendered latent by the polycarboxylic acid derivative (C) to the total epoxy groups contained in the epoxy-group containing polymer (A) and the epoxy-group containing compound (B) is in the range from 0.7 to 1.1, wherein a 6-membered ring of Formula (1′) is an alicyclic hydrocarbon.
