Silver halide photographic emulsion, method for producing thereof, and light-sensitive material using the same

A silver halide photographic emulsion produced by a method comprising the steps of:

• (a) producing a host emulsion comprising silver bromide or silver iodobromide hexagonal or triangular {111} tabular grains having an average silver iodide content (I.sub.1 mol %) of the entire silver halide grains of said host emulsion of 5 mol % or less, in which 60% or more of the projected area of said entire silver halide grains accounting for tabular grains having an aspect ratio of 3.0 or more;
• (b) dissolving a periphery of said tabular grains completely with an iodide ion being added to said host emulsion;
• and then
• (c) producing final tabular grains by reclaiming a periphery containing silver iodobromide from the region containing said periphery having been completely dissolved.

A silver halide photographic material comprising a support having provided thereon a photographic emulsion layer containing a silver halide photographic emulsion, said silver halide photographic emulsion being produced by a method comprising the steps of:

• (a) producing a host emulsion comprising silver bromide or silver iodobromide hexagonal or triangular {111} tabular grains having an average silver iodide content (I.sub.1 mol %) of the entire silver halide grains of said host emulsion of 5 mol % or less, in which 60% or more of the projected area of said entire silver halide grains accounting for tabular grains having an aspect ratio of 3.0 or more;
• (b) dissolving in a periphery of said tabular grains completely with an iodide ion being added to said host emulsion;
• and then
• (c) producing final tabular grains by reclaiming a periphery containing silver iodobromide from the region containing said periphery having been completely dissolved.
