摘要

PURPOSE:To obtain the silver halide color photographic sensitive material which imparts images having excellent color reproducibility and tone reproducibility by incorporating a silver chloride into the photosensitive material and further mixing specific silver halide emulsions. CONSTITUTION:The red-, green- and blue-sensitive silver halide emulsion layers A, B, C are provided on a base and the silver halide emulsions incorporated in the A, B, C are formed of silver chlorobromide emulsions having =95mol% silver chloride content. Further, the silver halide emulsions of the A and B are subjected to the spectral sensitization of the blue region so as to attain the range satisfying formulas I, II in a particle forming stage and/or chemical sensitizing stage; in addition, =2 kinds of the silver halide emulsions are mixed in the A and B in such a manner that the gammas of the A and B attain 0.6 to 1.3 times the gamma of the C in the photosensitive region of the C. In the formulas I, II, BSA, BSB and BSC denote the blue sensitivities of the A, B and C expressed by log (1/exposure) at 1.0 cyan, magenta and yellow optical density. The detail delineation of the color images having shades while having the bright color reproducibility is faithfully obtd. in this way.
