    • A silver halide photographic light-sensitive element is described comprising a support having thereon at least one silver halide emulsion layer, wherein at least one compound represented by formula (I) is incorporated in the silver halide emulsion layer or in another hydrophilic colloid layer: ##STR1## wherein X represents a hydroxy group or a group represented by ##STR2## wherein R.sup.2 and R.sup.3 (which may be the same or different) each reprsents hydrogen, an alkyl group, or an aryl group; R.sup.1 represents a sulfur-containing saturated heterocyclic group or a group represented by -A-S-B, wherein A represents an alkylene group and B represents hydrogen, an alkyl group, or an aryl group; and Z represents an atomic group forming a 5-membered or 6-membered unsubstituted or substituted carbocyclic ring.In the silver halide photographic light-sensitive element, the so-called "latent image fading" phenomenon is prevented without accompanying degradation of other photograhic properties.
    • 描述了一种卤化银照相感光元件,其包括其上具有至少一个卤化银乳剂层的载体,其中至少一种由式(I)表示的化合物引入卤化银乳剂层或另一亲水胶体层中: 图像(I)其中X表示羟基或由其表示的基团,其中R2和R3(可以相同或不同)各自代表氢,烷基或芳基; R1表示含硫的饱和杂环基或由-A-S-B表示的基团,其中A表示亚烷基,B表示氢,烷基或芳基; Z表示形成5元或6元未取代或取代的碳环的原子团。 在卤化银摄影感光元件中,防止所谓的“潜像褪色”现象,而不伴随着其它光致变色性能的降低。

    • A lithographic silver halide photographic light-sensitive material is described which scarcely exhibits colored fringe and black pepper, forms halftone dots of good quality whether a fresh or an exhausted developer is used for processing thereof, and which scarcely shows a drop in sensitivity even when a developer contaminated by a fixing solution is used; said material comprises a support and at least one lithographic silver halide emulsion layer, and containing in said emulsion layer or in another hydrophilic colliodal layer which does not contain silver halide emulsion at least one compound represented by formula (I) ##STR1## wherein M represents hydrogen, an alkali metal ion or --NH.sub.4.sup..sym. ; X represents --SO.sub.2 NHR', --COOM', --SO.sub.3 M', --OH or --CONH.sub.2, wherein M' represents hydrogen, an alkali metal ion or --NH.sub.4.sup..sym. ; and R' represents hydrogen or an alkyl group having from 1 to 3 carbon atoms; R represents hydrogen or an alkyl group having from 1 to 3 carbon atoms; and n represents 1 or 2.
    • 描述了几乎不显示有色边缘和黑胡椒的平版卤化银照相感光材料,即使使用新鲜或耗尽的显影剂进行处理,也形成质量好的半色调点,并且即使当 使用受固定液污染的显影剂; 所述材料包括载体和至少一个平版卤化银乳剂层,并且在所述乳剂层中或在不含有卤化银乳剂的另一亲水性乳液层中包含至少一种由式(I)表示的化合物(I) 其中M表示氢,碱金属离子或-NH4(+); X表示-SO 2 NHR',-COOM',-SO 3 M',-OH或-CONH 2,其中M'表示氢,碱金属离子或-NH 4(+)。 并且R'表示氢或具有1至3个碳原子的烷基; R表示氢或具有1至3个碳原子的烷基; n表示1或2。
