ABSTRACT:
A silver halide color photographic material comprising a support having coated thereon at least one silver halide emulsion layer, the silver halide color photographic material containing a photographic cyan dye forming coupler represented by the following general formula (I): ##STR1## wherein R.sub.1 represents an aliphatic group, an aromatic group, heterocyclic group or a substituted amino group; R.sub.2 and R.sub.3, which may be the same or different, each represents an aliphatic group, an aromatic group or a heterocyclic group, or R.sub.2 and R.sub.3 may combine with each other to form a ring; and X represents a group capable of beiing released upon an oxidative coupling with a developing agent (including a hydrogen atom).
The photographic cyan dye forming coupler has a high color forming rate and provides a high maximum color density even when a color developing solution which does not contain benzyl alcohol is used, and exhibits substantially no reduction in color density in the case of processing in a bleaching solution having a weak oxidation power or an exhausted bleaching solution.
The silver halide color photographic material containing the photographic cyan dye forming coupler can provide color images having excellent fastness and color reproducibility and less stain in white background area.
