An ink composition for roll printing is provided. The ink composition uses a solvent system having an evaporation rate (V) of at least 0.1 mg/cm&#xb7;min and an absorption rate (S) into a blanket of less than 3.412 mg/cm&#xb7;min. The use of the highly volatile solvent system can minimize swelling of the blanket without impairing the dispersibility of a pigment in the ink composition. Therefore, the uniformity of a pattern formed using the ink composition can be maintained and the formation of defects by the solvent system can be minimized.

A heat-curable ink composition and a color filter produced using the ink composition are provided. The ink composition and the color filter are highly resistant to heat and chemicals due to the use of a polyester resin prepared by polycondensation. In addition, unreacted anhydride groups are removed using a monohydric alcohol in the preparation of the ink composition to make the ink composition and the color filter very stable during storage.
