Method of preparing silver halide photographic emulsion |
摘要 |
A method of preparing a silver halide photographic emulsion comprising silver chloride as a principal component, which comprises adding to an aqueous solution of a hydrophilic colloid, an aqueous solution of a water-soluble silver salt and an aqueous solution of a water-soluble halide according to a simultaneous mixing method, and maintaining the rate of addition of the aqueous solution of a water-soluble silver salt and that of the aqueous solution of a water-soluble halide at a level not higher than the critical growth rate of silver halide grains and, at the same time, setting and maintaining the EAg value during the addition of the aqueous solution of a water-soluble silver salt and the aqueous solution of a water-soluble halide to a level not lower than 130 mV and not higher than 160 mV, said silver halide photographic emulsion being prepared in the presence of a water-soluble rhodium salt which is added during the course of emulsification and physical ripening of the emulsion.
