    摘要: The present invention relates to a method for preparing a silver halide photographic emulsion, comprising the steps of a) providing a nucleation medium comprising an aqueous composition based on a hydrophilic colloid and a non-ionic antifoaming agent; b) precipitating silver halide nuclei in said nucleation medium; c) growing said silver halide nuclei to form a silver halide photographic emulsion; and d) removing the non-ionic antifoaming agent from the nucleation medium by contacting the silver halide photographic emulsion resulting from step c) with a material that has surface lipophilic functions.
