摘要:
The present invention relates to an infrared curable ink composition for a color filter. The ink composition according to the present invention includes a melamine compound and an epoxy compound, and thus can be cured for a short time, thereby being used in the infrared curing process, and reducing the production process and time required for the color filter production. In addition, the color filter produced by the ink composition according to the present invention has excellent chemical resistance and heat resistance, thereby being applied to various electronic devices such as liquid crystal display device.
摘要:
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.
