Method for manufacturing a light-sensitive silver halide emulsion

A method for producing a silver halide photographic emulsion comprising the step of:

• reacting a water-soluble silver salt and at least one water-soluble halide salt containing chloride in aqueous solution in the presence of at least one compound represented by formulae (I) or (II):
• ##STR7## wherein A.sub.1, A.sub.2, A.sub.3 and A.sub.4, which may be the same or different, each represents a nonmetallic atomic group necessary for forming a substituted or unsubstituted heterocyclic ring which may be condensed with a benzene ring, said heterocyclic ring being selected from the group consisting of pyridine, imidazole, thiazole, oxazole, pyrazine and pyrimidine;
• B represents a divalent linking group;
• R.sub.1 and R.sub.2, which may be the same or different, each represents an alkyl group;
• X represents an anion necessary for charge balance;
• m is 0 or 1;
• and n is 0, 1, 2 or 3;
• to form light-sensitive silver halid grains having a silver chloride content of at least 50 mol %, selected from octahedral grains, tetradecahedral grains and tabular grains, wherein at least 30% of the surface area of said light-sensitive silver halide grains is composed of (111) planes.
