PURPOSE:To obtain the titled material capable of rapidly obtaining photographic characteristics of high sensitivity and contrast having >10 gamma value by incorporating an amine compd. or a quaternary onium salt and at least one of specific compds., to an emulsion layer or another constituting layer, in using a stable liquid developer. CONSTITUTION:The titled material has at least one layer of the silver halide photosensitive emulsion layers mounted on a substrate body, and contains a hydrazine derivatives in the emulsion layer and/or the another constituting layer. The emulsion layer or the another constituting layer contains the amine compd. or the quaternary onium salt and at least one compd. which does not have substantially the max. absorption at a visible range, and is shown by C-L-D wherein C is a group capable of promoting the adsorption to silver halide, D is an acidic group and L is a divalent binding group. |
