PURPOSE:To prevent the generation of fog in a treatment by a compact automatic developing machine by incorporating a photosensitive silver halide, an internally fogged silver halide emulsion and a specific compd. to the silver halide emulsion layer. CONSTITUTION:The silver halide emulsion layer contains the photosensitive silver halide, the internally fogged silver halide emulsion and the compd. shown by the formula in the titled material provided at least one layer of the silver halide emulsion layer on a substrate body. In the formula, Z is an atomic group necessary to form a 5-6 membered heterocyclic ring which may condense with an aromatic ring. Thus, the titled material having high sensitivity and excellent graininess and capable of preventing the generation of fog in the treatment by the compact automatic developing machine is obtd. |
