A color diffusion transfer photographic light-sensitive material comprising a support, at least one silver halide layer on the support, said emulsion layer being associated with a dye-providing compound, and an image-receiving layer on the same support as above or on another support, wherein said photographic light-sensitive material is able to provide a transferred dye image composed of a diffusible dye or its precursor released or derived from the dye-providing compound as a result of development under a strong alkaline condition in the presence of at least one meso ionic 1,2,4-triazolium-3-thiolate compound. In the present material, fog can be prevented efficiently without causing the problems of a reduction in sensitivity and a decrease in rate of development.
一种彩色扩散转移照相光敏材料,包括支撑体,在支撑体上至少有一层
银卤化物层,该乳剂层与
染料提供化合物相关联,并在与上述相同的支撑体或另一支撑体上具有图像接收层,其中该照相光敏材料能够在至少一种中性离子
1,2,4-三唑-3-
硫酸盐化合物的存在下,在强碱性条件下进行显影,释放或衍生自
染料提供化合物的可扩散
染料或其前体,形成转移
染料图像。在该材料中,可以有效地防止雾化,而不会导致感光度降低和显影速率降低的问题。
