| 摘要 |
The present invention relates to a colored photosensitive resin composition and, more particularly, to a colored photosensitive resin composition including a coloring agent (A), an alkali soluble resin (B) including a compound represented by chemical formula 1, a photopolymerizable compound (C), a photopolymerizable initiator (D) and a solvent (E). The acid value of the alkali soluble resin (B) is 30 to 150 mg KOH/g. The colored photosensitive resin composition has good sensitivity and adhesion, and the short of patterns may be hardly generated during performing a developing process. Thus, the productivity of a color filter is good, and a color filter formed by using the composition has good contrast, penetration ratio, chemical resistance, and sensitivity. In chemical formula 1, R1 is hydrogen or an alkyl group having 1 to 6 carbon atoms; R2 is an alkyl group, an alkenyl group, or an aryl group having 1 to 20 carbon atoms; R3 and R4 are independently an alkyl group, an alkenyl group, or an aryl group having 1 to 12 carbon atoms; A1 is an alkyl group or an alkenyl group having 1 to 4 carbon atoms as a divalent connecting group; and X is carboxylate (-COO^-), sulfonate (SO_3^-) or sulfate (-OSO_3^-). |
