ABSTRACT:
Siliver halide color photographic materials are disclosed which have high color-reproducibility and high color image-fastness and which are substantially free from variation with respect to sensitivity, gradation or color density as caused by variation of various factors in the development of the materials such as variation of the composition of the treating solution, the treating time or the treating temperature.
The present silver halide color photographic materials have at least one silver halide emulsion layer on a support and are characterized in that silver halide grains contained in the emulsion layer comprise silver bromide or silver bromochloride, about 50% or more of the total projected area of said silver halide grains are composed of tabular grains having an average aspect ratio of about 5 or more particularly 5 to 8, and the emulsion layer further contains at least one pyrazoloazole-type magenta coupler represented by general formula (I): ##STR1## wherein R.sup.1 represents a hydrogen atom or a substituent;
