摘要:
A silver halide photographic material having good spectral-sensitivity to laser rays, and which forms a high-sensitivity and high-contrast image by short-time exposure with high-intensity light. When processed with a reduced amount of replenisher, there is little fluctuation of photographic properties of the processed photographic material. The present invention relates to a silver halide photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer comprising a silver halide emulsion containing silver halide grains having a silver chloride content of 50 mol % or less, wherein the silver halide emulsion is spectrally sensitized with a spectral sensitizing dye selected from the group consisting of compounds represented by formulae (I), (II) and (III) and the silver halide emulsion is chemically sensitized with a selenium compound and a gold compound: ##STR1## where the substituent groups for formulae (I) to (III) are defined in the specification.
