Method for preparing photosensitive silver halide emulsions

摘要

The present invention is directed to a method for preparing a photosensitive silver halide emulsion comprising silver halide grains prepared by simultaneously introducing a solution of ammoniacal silver nitrate and a solution of an ammonium halide into a solution of gelatin and a second ammonium halide. The invention is also directed to photographic elements employing such silver halide emulsions.
