Provided is a thermosetting ink-jet ink composition, which has a superior jetting property upon printing in a piezoelectric element manner, produces color filters in a simpler process than the light-curable ink composition, and is superior in membrane hardness and uniformity in pixels. The thermosetting ink-jet ink composition comprises (a) 5-50 parts by weight of a copolymer having a weight average molecular weight of 10,000-80,000 of (1) a monomer having an epoxy group in the molecule or a polymer having an epoxy group in the chain and (2) a monomer having an ethylenic double bond except an epoxy group, (b) 0.1-5.0 parts by weight of an unsaturated carboxylic acid, (c) 5-60 parts by weight of a pigment, and (d) 20-80 parts by weight of an organic solvent.
