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.

摘要： A silver halide color light-sensitive material is described, which is increased in sensitivity, is adapted to form an image of high contrast, or is accelerated in development by incorporating a small amount of a specific compound which imagewise releases a foggant or a development accelerator. This compound is represented by the formula: Coup-(TIME).sub.n -FA (wherein Coup represents a coupler radical capable of undergoing a coupling reaction with an oxidized product of an aromatic primary amine developing agent; TIME represents a timing group which is eliminated from Coup by the coupling reaction and, thereafter, releases FA; n is 0 or 1; and FA represents a group which is eliminated from Coup in the coupling reaction when n is 0, whereas FA is released from TIME when n is 1. The FA has adsorption properties with respect to silver halide grains and also has a substantial fogging action with respect to the silver halide grains).
