A method for processing an imagewise exposed black-and-white negative silver halide photographic light-sensitive material comprising a support having provided thereon photographic layers including at least one silver halide emulsion layer, one of said photographic layers containing a hydrazine derivative, said method comprising;

Composition for developing a black-and-white silver halide photographic

A method of producing a silver halide photographic light-sensitive material is disclosed. The light-sensitive material comprises a support, provided thereon, a photographic layer including a silver halide emulsion layer and the photographic layer contains a hydrazine compound for forming an extremely high contrast image even when developed with a developer having a pH value of not higher than 11. The light-sensitive material is produced by the method comprising steps of

Method for producing a silver halide photographic light-sensitive

An improved process for producing a silver halide photographic material that has at least one light-sensitive silver halide emulsion layer on a support as well as at least one hydrophilic colloidal layer coated on both sides of the support. The process is characterized in that the hydrophilic colloidal layers on the two sides of the support are dried simultaneously and that a matting agent having a particle size of at least 4 .mu.m is incorporated in the outermost layer on both sides of the support in an amount of at least 4 mg/m.sup.2.
