摘要:
A process for manufacturing a silver halide color photographic material is disclosed. The photographic material comprises a blue light-sensitive layer-unit, a green light-sensitive layer-unit and a red light-sensitive layer-unit in which at least one of the light-sensitive layer-units comprises two or three silver halide emulsion layers being substantially the same in spectral sensitivity and different in speed from each other. The manufacturing process comprises steps ofproducing a high-speed silver halide emulsion having a largest average grain size among the silver halide emulsions to be used in the at least one light sensitive layer-unit,chemically sensitizing the high-speed silver halide emulsion, producing a low-speed silver halide emulsion having a smaller average grain size than that of the high-speed emulsion,chemically sensitizing the low-speed emulsion,mixing the chemically sensitized high-speed and the chemically sensitized low-speed emulsion in a ratio of from 5:95 to 50:50 by weight in terms of silver, andcoating the chemically sensitized high-speed emulsion and the mixture of the chemically sensitized high-speed emulsion and the chemically sensitized low-speed emulsion to form the at least one light-sensitive layer-unit.The photographic material is improved in adaptability to fluctuation of processing conditions.
