Abstract
A silver halide photographic light-sensitive material is disclosed, which comprises a support and provided thereon, a silver halide emulsion layer containing a crown ether having a 18-membered ring condensed with at least one aromatic ring and silver halide grains having a (100) face and satisfying the following inequality: 15.ltoreq.K wherein K is defined to be (intensity of a diffraction line attributed to a (200) face)/(intensity of a diffraction line attributed to a (222) face).
Claims7
A silver halide photographic light-sensitive material comprising a support and, provided thereon, a silver halide emulsion layer, containing silver bromochloride grains having a silver bromide content of 0.01 to 2 mol % and having a (100) face, and a crown ether having a 18-membered ring condensed with at least one aromatic ring, wherein said silver halide grains satisfy the following inequality:
- 15.ltoreq.K
- wherein K is defined to be (intensity of a diffraction line attributed to a (200) face)/(intensity of a diffraction line attributed to a (222) face), said intensity being measured by an X-ray diffraction method.
A silver halide photographic light-sensitive material comprising a support and provided thereon, a blue sensitive silver halide emulsion layer, a green sensitive silver halide emulsion layer and a red sensitive silver halide emulsion layer, each layer containing silver bromochloride grains having a (100) face and satisfying the following inequality:
- 15.ltoreq.K
- wherein K is defined to be (intensity of a diffraction line attributed to a (200) face)/(intensity of a diffraction line attributed to a (222) face), said intensity being measured by an X-ray diffraction method, and said red sensitive layer containing a crown ether having a 18-membered ring condensed with at least one aromatic ring in an amount of 1.times.10.sup.-6 to 1.times.10.sup.-1 mol per mol of silver and a red-sensitive sensitizing dye in an amount of 2.times.10.sup.-8 to 1.times.10.sup.-2 mol per mol of silver, said red sensitive dye being represented by the following Formula (I) or (II):
