ABSTRACT:
A color photographic element comprising a support bearing at least one photographic silver halide emulsion layer and a combination of at least two couplers (A) and (B), coupler (A) capable upon reaction with oxidized developer of forming a compound that is washed out of the photographic element during photographic processing and capable of releasing a photographic development inhibitor or a timing group having a photographic development inhibitor, the timing group capable of providing timed release of said photographic development inhibitor and coupler (B) capable upon reaction with oxidized developer of forming a compound that is not washed out of the photographic element during photographic processing and capable of releasing a photographic development inhibitor with or without time delay. Such a color photographic material enables formation of improved color images.
