PURPOSE:To accelerate development and increase effective sensitivity by photoprocessing the silver halide photographic material having undergone exposure with the developing solution contained with the specific compounds. CONSTITUTION:The compounds expressed by formula I [A, B, are H, formula II (R<1> is alkylene; R<2> is alkyl, alkenyl, cycloalkyl, aryl, heterocycles), alkyl, alkenyl, cycloalkyl, aryl, heterocycles; D is H, alkyl (D and B may combine to form combined nitrogen contained heterocyclic rings); at least one of A, B is formula II], e.g., formulas III, IV, are added at ratios of about 0.001 to 200g/l (preferably 0.01 to 10g/l to the developing solution (or preprocessing solution) and the mixture is used. |
