Ink composition for color filter, method for preparing a color filter using the same, and color filter

摘要

Disclosed is a color filter ink composition that includes an acrylic-based copolymer resin including repeating units represented by a particular chemical formula, a polymerizable monomer, a pigment, and a solvent. According to the present invention, the color filter ink composition can have excellent ejection properties and ejection stability by using a new acrylic-based copolymer resin as a binder resin, and also can have excellent storage stability, so that it can be used for a long period. In addition, a pattern formed using the color filter ink composition can have improved heat resistance, chemical resistance, and film strength.
