PHOTOSENSITIVE RESIN COMPOSITION FOR COLOR FILTER AND COLOR FILTER USING SAME

摘要

PURPOSE: A photo-sensitive resin composition for a color filter and the color filter using the same are provided to improve light resistance characteristic, heat resistance characteristic, and durability. CONSTITUTION: A photo-sensitive resin composition for a color filter includes a coloring agent, an acryl-based binder resin, an acryl-based photo-polymerizable monomer, a photo-polymerization initiator, and a solvent. The coloring agent includes a diaminopyridine azo-based dye represented by chemical formula 1. The absorption wavelengths of the dye are in a range between 450 and 550nm. In chemical formula 1, R1 is a substituted or non-substituted C1 to C20 alkyl group, a C2 to C20 alkylaminoalkylsulfonyl group, or a C1 to C20 alkyl group in which at least one of -CH_2- is substituted with -SO_2-, -O-, or -NR-; in R1, R is a hydrogen element or a C1 to C6 alkyl group; R2 is a substituted or non-substituted C6 to C30 arylene group or a substituted or non-substituted C6 to C30 heteroarylene group; R3, R4, R5, R'4, and R'5 are respectively hydrogen elements, substituted or non-substituted C1 to C20 alkyl groups, C1 to C20 alkyl groups in which at least one of -CH_2- is substituted with -SO_2-, -O-, or -NR-, substituted or non-substituted C3 to C20 cycloalkyl groups, substituted or non-substituted C2 to C20 alkenyl groups, substituted or non-substituted C6 to C30 aryl groups, substituted or non-substituted C2 to C30 heterocyclic groups, sulfoylalkyl groups, sulfonylaryl groups, acyl groups, carboxylic groups, sulfone groups, or carbamoyl groups; R6 is a hydrogen element, a halogen group, or a cyano group; in R2 to R'5, R is a hydrogen element or a C1 to C10 alkyl group, R' is a hydrogen element or a C1 to C10 alkyl group, and R'' is a C6 to C16 aryl group.
