DEVELOPING SILVER HALIDE IN THE PRESENCE OF SULFITE ION, P-DIHYDROXYBENZENE DEVELOPING AGENT, AN ARYL SUBSTITUTED HYDRAZINE DERIVATIVE AND A POLYALKYLENE OXIDE

摘要

?-2A-19480/KT/78 A process for producing a high contrast photographic image comprising developing an image-wise exposed silver halide photographic light-sensitive material comprising a support having thereon at least one silver halide emulsion layer with a developer containing (a) free sulfite ion in a concentration of at least 0.18 mol/? and (b) as substantially the only developing agent a dihydroxybenzene in the presence of (i) at least one compound represented by the following general formula (I); R1NHNHCOR2 (I) wherein R1 represents an aryl group; R2 represents a hydrogen atom, a phenyl group or an unsubstituted alkyl group having 1 to 3 carbon atoms and (ii) at least one polyalkylene oxide having a molecular weight of at least 600 or a derivative thereof.
