Color photographic elements containing yellow colored magenta dye forming masking couplers |
摘要 |
A multilayer silver halide color photographic element comprising a support bearing a light-sensitive silver halide emulsion layer and a non-diffusible yellow-colored magenta dye-forming masking coupler wherein the masking coupler is a 2'-hydroxy-5'-substituted-4-phenylazo-5-pyrazolone. The masking coupler has good coupling activity and desirable hues, and can be obtained in good yields by simple syntheses.
