Core-shell dye, photosensitive resin composition including the same, and color filter

A core-shell dye, comprising:

• a core represented by Chemical Formula 1;
• and
• a shell represented by Chemical Formula 2, the shell surrounding the core,
• wherein:
• in Chemical Formula 1,
• L1 to L4 are each independently a single bond, a substituted or unsubstituted C1 to C20 alkylene group, or a substituted or unsubstituted C6 to C30 arylene group;
• and
• R1 to R4 are each independently hydrogen, 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 C30 aryl group;
• provided that at least one of R1 and R2 is substituted with a substituted or unsubstituted epoxy group at a terminal end and at least one of R3 and R4 is substituted with a substituted or unsubstituted (meth)acrylate group at a terminal end;
• in Chemical Formula 2,
• L′ and L″ are each independently a single bond or a substituted or unsubstituted C1 to C10 alkylene group;
• Z1 and Z2 are each independently *—CR—* or a nitrogen atom, in which R is a hydrogen atom or a substituted or unsubstituted C1 to C10 alkyl group;
• X1 and X2 are each independently a halogen or a substituted or unsubstituted C1 to C20 alkyl group;
• l and m are each independently an integer of 0 to 4;
• and
• n is an integer of 2 or more.
