    • A silver halide photographic light-sensitive material is disclosed. The light-sensitive material comprises a support having thereon a photographic layer including a silver halide emulsion layer wherein the outermost surface of said photographic layer has a pH value of from 5.4 to 5.9 and said silver emulsion layer contains a compound represented by the following formula I; ##STR1## wherein R.sub.1 is an alkyl group, a cycloalkyl group or an aryl group; R.sub.2 is an alkyl group, a cycloalkyl group, an acyl group or an aryl group; R.sub.3 is a substituent, n is 0 or 1; X.sub.1 is a substituent capable of splitting off upon coupling reaction with the oxidation product of a color developing agent; and Y.sub.1 is an organic group. The light-sensitive material is excellent in stability during storage and gives stable photographic characteristics even when pH value of developer is varied.
    • 公开了一种卤化银照相感光材料。 感光材料包括其上具有包括卤化银乳剂层的照相层的支撑体,其中所述照相层的最外表面的pH值为5.4至5.9,并且所述银乳剂层含有由下式I表示的化合物 ; (I)其中R1是烷基,环烷基或芳基; R2是烷基,环烷基,酰基或芳基; R3是取代基,n是0或1; X1是能够与彩色显影剂的氧化产物偶联反应时分解的取代基; Y1是有机基团。 感光材料在保存期间的稳定性优异,并且即使改变显影剂的pH值也能提供稳定的照相特性。
