摘要： Disclosed herein is a silver halide photographic light-sensitive material comprising at least one layer made of a silver halide emulsion comprising a dispersion medium and silver halide grains dispersed in the dispersion medium. Each of the silver halide grains contains a metal or metal ions other than silver. The emulsion has been chemically sensitized in the presence of a tellurium compound which has a pseudo-first order reaction rate constant k of 1.times.10.sup.-8 to 1.times.10.sup.-0 min.sup.-1. The metal is at least one polyvalent metal selected from the group consisting of Ir, Rh, Pd, Ru, Pt, Os, Fe, Ni and Co. The metal ions are ammonium salt, acetate, nitrate, sulfate, phosphate, hydroxide, or complex salt of the metal. Telluroketones or phosphinetellurides is used as the tellurium compound. It is desirable that the silver halide emulsion is a monodispersed emulsion having a variation coefficient of 22% or less. The silver halide photographic light-sensitive material has its photographic properties, particularly the gradation and the reciprocity, improved, with no reduction of its sensitivity.

摘要： A silver halide photographic material composed of a support having thereon at least one silver halide emulsion layer containing substantially normal silver halide grains having a (111) plane and a (100) plane and capable of preferentially forming a latent image on the (100) plane; the (111) plane occupying at least about 40% of the surface of the grains or the (100) plane occupying more than about 60% of the surface of the grains; provided that when the (111) plane occupies at least about 40% of the surface of the grains, the grains are spectrally sensitized with (a) at least one spectral sensitizing dye selectively adsorbed more on the (100) plane than on the (111) plane, or (b) at least one spectral sensitizing dye selectively adsorbed more on the (111) plane than on the (100) plane. Since most of a sensitizing dye and the site where a latent image is formed can be separated on the surface of silver halide grains, the photographic material exhibits high sensitivity even when developed with a developing solution having low solubility.
