To provide an ink composition for ink jet recording and a color filter substrate, which have low viscosity while maintaining durability, and further have good viscosity stability and ejection stability over time. An ink composition has a general formula (1) in a vinyl polymer main chain: [X 1 is an acryloyl group, amide group, ether group, vinyl ester group, X 2 is a (poly) ether group, X 3 is a polyester group, and Y 1 is a carboxyl group-containing phenyl derivative group] A vinyl dispersant, a pigment, a heat-reactive compound, and an organic solvent containing a content unit in an amount of 0.3 to 3.0 in average per molecule of the vinyl polymer are included. The color filter substrate carries a printing layer made of the ink composition for ink jet recording. [Selection figure] None |
