【Task】 Containing finely dispersed pigment at a high concentration, and at the same time, physical properties (such as low viscosity) that can be stably ejected to a desired position on the substrate by an ink jet method, resistance as a color filter (heat resistance / resistance) To provide an ink composition having a solvent property. [Solution] In the ink composition for ink jet recording comprising the resin-type dispersant (F), the pigment (P), the heat-reactive compound (G), and the organic solvent (H), the resin-type dispersant (F) has one end. Isocyanate group of urethane prepolymer (E) having isocyanate groups at both ends, obtained by reacting the hydroxyl group of vinyl polymer (A) having two hydroxyl groups in the region with the isocyanate group of diisocyanate (B) An ink composition for inkjet recording, which is a resin-type dispersant (F1) obtained by reacting at least a primary and / or secondary amino group of an amine compound containing at least a polyamine (C).
