    摘要： A silver halide photographic material having increased sensitivity and gradient and being free from fog formation on storage, comprising a support and an emulsion layer containing very fine silver halide grains and containing a nitrogen-containing heterocyclic organic compound having a hydroxylamino group, such as 2-hydroxylamino-4,6-di(ethylamino)-1,3,5-triazine or 2,4-di(hydroxylamino)-6-diethylamino-1,3,5-triazine. The photographic material is useful for recording fine images with a superior sharpness, and the incorporation of the heterocyclic compound increases the sensitivity in spite of the fine grain size of the silver halide.
