A magenta dye-forming coupler for photographic material is disclosed. The coupler is a polymer derived from a monomer having the formula: ##STR1## R 1 represents hydrogen or a substituent, X represents hydrogen or a group capable of being released by a coupling reaction with an oxidized aromatic primary amine developing agent, n Z represents the atoms necessary to complete a heterocyclic ring, n L represents a divalent linking group, n A represents --CONH--, --COO--, --O--, --OOC--, --NHCO--, --NHCONH--, --NHSO 2 --, or a substituted or unsubstituted phenylene group, n D represents --O--, --NR"--, or --CONR"--, n R represents a substituted or unsubstituted aliphatic or a substituted or unsubstituted aromatic substituent, having at least 6 carbon atoms, n R' represents H, substituted or unsubstituted lower alkyl of from 1 to 4 carbon atoms, carboxyl, or halogen, and n R" represents substituted or unsubstituted: alkyl, aryl, or acetyl. |
