Method for preparing silver halide photographic emulsion.

摘要

There is disclosed a method for preparing a silver halide photographic emulsion by use of an ammoniacal silver nitrate solution in a double-jet manner, characterized in that the method comprises the step of keeping essentially constant the solubility of the silver halide in a silver halide photographic emulsion during the crystalization of said silver halide after 10 mole % of said total silver halide crystals have been precipitated, and/or during a physical-ripening process.

The method according to the present invention can provide a monodispersed silver halide photographic emulsion which has a high sensitivity, i.e., which comprises silver halide having a relatively large crystal size.
