摘要 |
<p>@ A silver halide photographic material is described, comprising a support, at least one silver halide emulsion layer, and one or more light-insensitive hydrophilic colloid layers, wherein said silver halide emulsion layer or said light-insensitive hydrophilic colloid layer contains a hydrazine derivative, and the photographic material has a film surface pH not higher than 5.8 on the side of said emulsion layer inclusive of said light-insensitive hydrophilic colloid layer; in another aspect, this invention is directed to a method for forming an ultrahigh contrast negative image, comprising exposing said photographic material imagewise, followed by development processing of the same with a developer containing at least 0.15 mil/liter of sulfite ion and having a pH of from 10.5 to 12.3.</p> |
