PHOTOSENSITIVE RESIN COMPOSITION FOR COLOR FILTER AND COLOR FILTER USING THE SAME

摘要

A photoresist resin composition for a color filter, and a color filter manufactured by using it are provided to prevent the remaining of residue on the nonexposure part and to form the ultra-fine pixel. A photoresist resin composition for a color filter comprises an alkali soluble resin; a polymerizable monomer; a polymerization initiator; a pigment; a dispersant; and a solvent, wherein the dispersant is an amino group-containing maleic acid copolymer having a urethane group and a long chain branched group. Preferably the dispersant is formed by the combination of the structural units represented by the formula 1 and the formula 2.
