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.
