ABSTRACT:
A silver halide photographic light-sensitive material for photomechanical process is described, comprising a support, at least one photosensitive silver halide emulsion layer thereon, and at least one light-insensitive upper layer on the emulsion layer. At least one of the light-insensitive upper layers contains a compound having an electric charge and being substantially insoluble in water but soluble in a water-miscible organic solvent; a method for a reducing treatment is also described, which comprises bringing a silver image formed on the light-sensitive material into contact with a reducer through the light-insensitive upper layer containing the aforesaid compound.
