ABSTRACT:
A silver halide photographic light-sensitive material is disclosed, which is suitable for contact printing in photomechanical process and capable of being handled in daylight room. The light-sensitive material comprises a support having thereon a silver halide emulsion layer containing a silver halide emulsion and a hydrazine compound or a tetrazolium compound, a layer being provided on the surface of said emulsion layer farther from said support and containing a compound having a maximum spectral absorption at a wavelength of at least 50 nm longer than that of the maximum spectral sensitivity of said silver halide emulsion, and a layer being interposed between said support and said emulsion layer and containing a macromolecular compound having a heterocyclic group having a sulfo group or an alkylsulfo group. The light-sensitive material is excellent in reverse-text quality and inhibited in formation of pin-holes.
