摘要： A process of producing silver halide grains by supplying an aqueous solution of a water-soluble silver salt, an aqueous solution of a water-soluble halide, and an aqueous solution of a protective colloid to a mixer disposed outside of a reaction vessel containing an aqueous solution of a protective colloid. The protective colloid contains nuclei of silver halide grains for causing the crystal growth of silver halide grains. The process further includes mixing the aqueous solutions to form fine, silver halide grains, and immediately supplying the fine grains to the reaction vessel to perform the crystal growth of silver halide grains in the reaction vessel. The temperature of the aqueous solution of the protective colloid in the mixer is kept below 40°C. Further, a process of producing a photographic emulsion by supplying an aqueous solution of a water-soluble silver salt and an aqueous solution of a water-soluble halide to a mixer disposed outside of a reaction vessel for causing the nucleus formation and/or the crystal growth of silver halide grains while controlling the flow rates thereof. The process further includes the steps of: mixing the solutions while controlling the rotational speed of a propeller of the mixer to form fine, silver halide grains; immediately supplying the fine grains into the reaction vessel to perform the nucleus formation and/or the crystal growth of silver halide grains in the reaction vessel. The aqueous solution of the water-soluble silver salt and the aqueous solution of the water-soluble halide are previously diluted with a solution of a protective colloid and then supplied to the mixer.

摘要： A silver halide photographic material and a process for its preparation are disclosed. This material has a silver halide emulsion layer containing photosensitive silver halide grains obtained by adding previously prepared fine silver halide grains to a reaction vessel for formation of grain nuclei and/or growth of crystals to thereby form nuclei and/or allow crystals to grow in said reaction vessel and subjecting to reduction sensitization. It has a high photographic speed, suffers less fogging and gives good graininess.
