ABSTRACT:
A novel silver halide photographic material is provided comprising a support having provided thereon at least one silver halide emulsion layer and containing at least one polyoxyethylenic compound in the emulsion layer or at least one other hydrophilic colloid layer, wherein silver halide grains contained in the emulsion layer are chemically sensitized in the presence of a water-soluble sensitizing dye having a solubility in 20.degree. C. water of 0.2 g/100 ml H.sub.2 O or more, or said water-soluble sensitizing dye is added to the silver halide emulsion after chemical sensitization and before coating. Such a water-soluble sensitizing dye is preferably selected from methine dyes and styryl dyes such as a cyanine dye, a merocyanine dye, a hemicyanine dye, a rhodacyanine dye, an oxonol dye, and a hemioxonol dye.
