Color photographic materials containing polymeric couplers.

摘要

Color photographic materials comprise a support bearing a silver halide emulsion and at least one water-dispersible polymeric coupler. The polymeric coupler is formed by polymerization of a mixture of at least one ethylenically unsaturated coupler monomer containing a dye-forming coupler moiety and at least one ionic monomer containing an ionizable functional group, in a water-miscible organic solvent. The polymeric coupler contains less than 10 weight percent of the ionic monomer.
