A silver halide photographic light-sensitive material having a high sensitivity and capable of forming an image with an excellent quality and gradation.

摘要

There is disclosed a silver halide photographic light-sensitive material having an excellent interimage effect and gradation property. The light-sensitive comprises at least one light-sensitive layer containing silver bromoiodide emulsion consisting primarily of the twinned grains, wherein in an X-ray diffraction diagram which is obtained by subjecting the silver bromoiodide grains to a (420) X-ray diffraction with a CuK alpha ray, an intercept between the intersection points of a maximum peak diagram and a line drawn horizontally at a point of 0.13 times the height of the maximum peak corresponds to not less than 1.5 degree of a diffraction angle (2 theta ).
