Abstract
A colored curable composition including a polymer dye in which the polymer dye is one or more members selected from the group consisting of a copolymer of at least one of a dye monomer represented by the following formula (P) and a colorless monomer having at least one ethylenic double bond, and a polymer derived from the dye monomer represented by the following formula (P). In formula (P): Ra1, Ra2 are H, an aliphatic group, an aryl group, or a heterocyclic group; L1 is represented by (L-1) to (L-4); i=0 or 1; Q is represented by formula (1), wherein: Ra3, Ra4 are H, an aliphatic group, an aryl group, or a heterocyclic group; R1 is an aliphatic group, aryl group, heterocyclic group, acyl group, or an aliphatic oxycarbonyl group; R2 is H or a substituent; X1 is —CR3═, or N(R3 is H, or a substituent); and A is a coupler residue.
