ABSTRACT:
A silver halide photographic light-sensitive material comprising a support having thereon a silver halide emulsion layer which comprises silver halide grains containing at least silver chloride and spectrally sensitized to infrared rays with at least one dye selected from a tricarbocyanine dye and a dicarbocyanine dye having a 4-quinoline nucleus, wherein the silver halide emulsion layer contains from 0.0003 mol to 0.01 mol per mol of silver of a water-soluble bromide.
The silver halide photographic light-sensitive material has high sensitivity in an infrared spectral region which does not substantially change during the preservation of the photographic light-sensitive material.
