PURPOSE:To obtain the titled material having a good raw shelf life and capable of a rapid treatment by providing an emulsion layer composed of the silver halide particle having substantially (100) plane on the titled material, and by incorporating a specific compd. to a photographic constituting layer. CONSTITUTION:At least one layer of the silver halide emulsion layers is composed of a layer comprising the silver halide particle having substantially (100) plane. At least one layer of the photographic constituting layers comprises one or more kinds of a precursor of 3-pyrazolidones shown by formulas I and II. In the formulas, R<1> and R<2> are each H or alkyl group, R<3> is halogen atom, alkyl or aryl group, R<4> is H or aryl group, (n) is 0-5, X and Y are each a group capable of cleaving by hydrolysis. Thus, the titled material having the improved treating stability and raw shelf life is obtd. |
