Patent ID: 8486591

Claim:
A color filter photosensitive resin composition comprising (A) an acryl-based binder resin having at least one carboxyl group; (B) an acryl-based photopolymerizable monomer; (C) a photopolymerization initiator; and (D) a solvent, wherein at least one of the acryl-based binder resin or the acryl-based photopolymerizable monomer includes a monomer including a blue dye functional group represented by the following Chemical Formula 1: wherein in the above Chemical Formula 1, M is a transition element, X 1 to X 4 are each independently hydrogen or a group represented by the following Chemical Formula 2, provided that at least one of X 1 to X 4 is represented by the following Chemical Formula 2, R 1 to R 4 are each independently hydrogen or C1 to C7 alkyl, and m1 to m4 and n1 to n4 are each independently integers ranging from 0 to 4, wherein m1+n1, m2+n2, m3+n3, and m4+n4 are 4, wherein in the above Chemical Formula 2, X is substituted or unsubstituted C2 to C12 hydrocarbon, Z is NH or oxygen, and Y is hydrogen or C1 to C7 alkyl, wherein when the acryl-based binder resin (A) includes the blue dye functional group, the acryl-based binder resin (A) comprises a copolymer of i) a first ethylenic unsaturated monomer including at least one carboxyl group, ii) a second ethylenic unsaturated monomer that is copolymerizable with the first ethylenic unsaturated monomer, and iii) a third ethylenic unsaturated monomer including the blue dye functional of Chemical Formula 1 in an amount of about 1 to about 70 wt % based on the total weight of the acryl-based binder resin.
