    • 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.
    • 描述了一种卤化银照相感光材料,其包括载体,在载体上的至少一层光敏卤化银乳剂层和设置在乳剂层上的至少一层不敏感的顶层,其中至少一个 乳剂层和其它构成层含有由通式(I)表示的化合物,其中R为取代或未取代的芳基,R 2为氢原子,取代或未取代的芳基,取代或未取代的烷基,取代或未取代的 未取代的烷氧基或取代或未取代的芳氧基,G为羰基,磺酰基,亚磺酰氧基,磷酰基或N-取代或未取代的亚氨基,并且其中所述至少一个不敏感的顶端 层被硬化以具有比乳剂层长至少50秒的熔化时间。 该材料能够形成与稳定的处理溶液具有超强对比度的负像。
