Abstract

Disclosed is a silver halide photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer, wherein the silver halide emulsion is produced in the presence of a polyalkylene oxide group-containing organopolysiloxane. The emulsion being produced in the presence of the defoaming agent is prevented from being foamed in a stirrer rotating at an elevated rotation speed. The stirring performance of the stirrer is enlarged, and the conditions for forming the silver halide grains can be controlled more uniformly. The photographic properties of the emulsion are improved and it is easy to scale up the production of the emulsion.
