摘要:
A negative-working type silver halide photographic material comprising a support having thereon at least one light-sensitive silver halide emulsion layer containing a hydrazine derivative, wherein the emulsion layer or another hydrophilic colloidal layer provided on the support contains at least one redox compound capable of releasing a development inhibitor upon oxidation, and the silver halide emulsion comprises monodispersed silver halide grains comprising 50 mol % or more of silver chloride.
摘要:
This invention relates to a silver halide photographic element capable of quickly forming direct positive images when using a processing solution having a high stability, and to an image forming process using the photographic element. More specifically, the invention relates to a silver halide photographic element for compute output (light-sensitive film for COM) and also to an image forming process using the photographic element.
摘要:
A silver halide photographic light-sensitive material is described, comprising a support, at least one light-sensitive silver halide emulsion layer on the support, and at least one light-insensitive top layer provided on the emulsion layer, wherein at least one of the emulsion layer and other constituent layers contains a compound represented by the general formula (I) wherein R is a substituted or unsubstituted aryl group, R 2 is a hydrogen atom, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkoxy group, or a substituted or unsubstituted aryloxy group, and G is a carbonyl group, a sulfonyl group, a sulfoxy group, a phosphoryl group, or an N-substituted or unsubstituted imino group and wherein said at least one light-insensitive top layer is hardened so as to have a melting time at least 50 seconds longer than that of the emulsion layer. This material enables the formation of a negative image having super contrast with a stable processing solution.
摘要:
@ 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.
