发明名称 Process for the preparation of silver halide photographic element
摘要 The present invention relates to a process for the manufacturing of a silver halide element comprising a silver halide emulsion-making step, a chemical or optical sensitization step, and a silver halide emulsion coating step, characterized in that the process comprises the step of adding to the silver halide emulsion, after the chemical or optical sensitization step and before the coating step, an aryl compound having at least two substituents each of these represented by an hydroxyl group and/or a sulfonic group in an amount of less than 0.03 moles per mole of silver. The aryl compound increases the speed to Dmin ratio when used in a silver halide element.
