摘要： A silver halide photographic light-sensitive material for plate making is disclosed. The material is comprised of a support base having thereon a sensitive silver halide emulsion layer and at least one upper insensitive layer having a melting time longer than the melting time of the sensitive silver halide emulsion layer. A method of reduction treatment for such silver halide light-sensitive material is also disclosed. The sensitive materials have excellent aptitude for reduction treatment and do not deteriorate even if the amount of silver per unit area is relatively small.
