alcohol group, an amino group, a nitro group, a hydroxyl group, a phenyl group or an acrylic group; a polymer thereof; or a mixture thereof. The use of the melamine compound in the ink composition prevents reduction of contrast ratio after high-temperature treatment and is effective in further improving the dispersibility of the ink. Further provided is a color filter produced by using the ink composition.
