Silver halide emulsion and silver halide photographic material using the same

A silver halide photographic material comprising a support and at least one silver halide emulsion is coated on at least one side of the support, wherein the silver halide emulsion comprises at least a dispersing medium and silver halide grains, wherein the silver halide grains have an AgCl content of from 30 mol % to 100 mol %;

• at least 30% of the sum of the projected area of the silver halide grains are tabular grains which satisfy the following conditions (i) to (v):
• (i) the tabular grains have {100} faces as major faces;
• (ii) the tabular grains have an aspect ratio (circle-equivalent diameter/thickness) of from 2.0 to 2.5;
• (iii) the tabular grains have an average thickness of from 0.02 .mu.m to 0.3 .mu.m;
• (iv) the tabular gains have an average major face edge length ratio of from 1 to 5;
• and
• (v) the tabular grains have been grown from intermediate grains which have two dislocation lines extending from about the nucleus until the intermediate grains have a projected area of about 75% or more of the projected area of the finished tabular grains, wherein the angle made by the two dislocation lines is from 5.degree. to 85.degree. when viewed in a direction perpendicular to the major face of the tabular grain.
