    摘要： The present invention relates to a process of preparing a photosensitive silver halide emulsion. In this process, an emulsion comprising an acid substituted organic ripening agent and a dispersing medium is prepared. Silver halide grains are then permitted to grow in the emulsion at a pH of from about 2 to about 4.6 to accelerate the growth of the silver halide grains. Subsequently, the pH of the emulsion is adjusted to a value of about 5.3 to about 7 to repress grain growth, to prevent interference with dye sensitization, and to limit fog formation, particularly during storage of the coated emulsion.
