PURPOSE:To improve the storage and the consumption of silver of the titled material by incorporating a specific compd. to the green-sensitive silver halide emulsion layer, and a specific DIR compd. to the photographic constituting layer respectively. CONSTITUTION:The green-sensitive silver halide emulsion layer comprises the pyrazolotriazole type Mazenta coupler shown by formula I, In the formula, X is a halogen atom or a monovalent org. radical capable releasing by the coupling reaction with the oxidant of the developing agent, R1-R4 are each a hydrogen atom, a halogen atom or an org. group such as an alkyl group. The DIR compd. shown by formula II is added to the sensitive silver halide emulsion layer and/or the non-sensitive photographic constituting layer, and for example, is added to the one or more than two layers of the multilayer colored photographic sensitive materials comprising the blue-sensitive silver halide emulsion layer, the green-sensitive silver halide emulsion layer and the red-sensitive silver halide emulsion layer whereby the raw storage of the titled material and the consumption of silver used in the titled material are improved. |
