Ink composition for color filter

Abstract

An ink composition for a color filter is provided. The ink composition comprises a pigment, a binder resin, a polymerizable monomer and a melamine compound. The melamine compound has a weight average molecular weight of 126 to 5,000. The melamine compound is represented by Formula 1: wherein R1, R2, R3, R4, R5 and R6 are each independently a hydrogen atom or a group including a C1-C6 alkyl group, a C1-C6 alkoxy group, a carboxyl group, a C1-C6 ether group, a C1-C6 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.
