Abstract (en)

Disclosed is a process for developing a silver halide color reversal photographic material comprising a support having provided thereon at least one red-sensitive silver halide emulsion layer, green-sensitive silver halide emulsion layer and blue-sensitive silver halide emulsion layer, wherein at least one silver halide emulsion layer contains tabular silver halide grains having an aspect ratio of at least 5 occupying at least 50% of all silver halide grains existing in the same layer as a projected area, and having a mean sphere-corresponding grain size of 0.30 mu m or less, which comprises developing said color reversal photographic material with a black-and-white developing solution for 100 seconds or less, thereby giving the sufficient multilayer effect even in processing in which the black-and-white developing time is short.
