Patent number: 8133962Abstract: 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.Type: GrantFiled: August 26, 2008Date of Patent: March 13, 2012Assignee: LG Chem, Ltd.Inventors: Dae Hyun Kim, Han Soo Kim, Mi Ae Kim, Dong Myung Shin, Jae Joon Kim, Jin Woo Cho, Ji Su Kim, Mi Kyoung Kim, Min A. Yu, Min Young Lim, Sung Hyun Kim
