Photosensitive resin composition, photosensitive resin layer using the same and color filter

A photosensitive resin composition, comprising:

• a colorant that includes:
• a first green dye having a core-shell structure in which the core is represented by Chemical Formula 1, and
• a second green dye represented by Chemical Formula 2, a weight ratio of the first green dye to the second green dye in the colorant being about 1:9 to about 7:3;
• a binder resin;
• a photopolymerizable compound;
• a photopolymerization initiator;
• and
• a solvent,
• wherein, in Chemical Formula 1 and Chemical Formula 2,
• R1 to R4 are each independently a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C3 to C20 cycloalkyl group, or a substituted or unsubstituted C6 to C20 aryl group, provided that at least one of R1 to R4 is a substituted C1 to C20 alkyl group, a substituted C3 to C20 cycloalkyl group, or a substituted C6 to C20 aryl group that is substituted with a substituted or unsubstituted acrylate group, and
• R13 to R28 are each independently a hydrogen atom, a halogen atom, a substituted or unsubstituted C1 to C20 alkyl group, a substituted or unsubstituted C3 to C20 alkoxy group, a substituted or unsubstituted C6 to C20 aryl group, or a substituted or unsubstituted C6 to C20 aryloxy group.
