Process for developing silver halide colour reversal photograhic material |
(57) 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 µm 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.
