Abstract
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.
