Lithographic silver halide photographic light-sensitive material

摘要

A lithographic silver halide photographic light-sensitive material is described which scarcely exhibits colored fringe and black pepper, forms halftone dots of good quality whether a fresh or an exhausted developer is used for processing thereof, and which scarcely shows a drop in sensitivity even when a developer contaminated by a fixing solution is used; said material comprises a support and at least one lithographic silver halide emulsion layer, and containing in said emulsion layer or in another hydrophilic colliodal layer which does not contain silver halide emulsion at least one compound represented by formula (I) (I) wherein M represents hydrogen, an alkali metal ion or -NH4(+); X represents -SO2NHR', -COOM', -SO3M', -OH or -CONH2, wherein M' represents hydrogen, an alkali metal ion or -NH4(+); and R' represents hydrogen or an alkyl group having from 1 to 3 carbon atoms; R represents hydrogen or an alkyl group having from 1 to 3 carbon atoms; and n represents 1 or 2.
