    • An image formation method by silver salt diffusion transfer is described, which comprises subjecting a photosensitive element containing at least one photosensitive silver halide emulsion layer to image exposure, then developing the photosensitive element by use of an alkali processing composition containing a solvent for a silver halide to turn at least a part of unexposed silver halide of the photosensitive silver halide emulsion layer into a transferable silver complex salt, transferring at least a part of the transferable complex salt to a silver precipitating nucleus-containing image receiving layer to form an image on the silver precipitating nucleus-containing image receiving layer, and separating the silver precipitating nucleus-containing image receiving layer from the photosensitive element after image formation to obtain the image, wherein the image is formed in the presence of at least one compound represented by the following formula (I) and at least one compound represented by the following formula (II): ##STR1## wherein R represents a hydrogen atom, an unsubstituted alkyl group, an unsubstituted alkenyl group or -L.sub.2 -A.sub.2 ; L.sub.1 and L.sub.2 each represents an alkylene group; A.sub.1 and A.sub.2 each represents a carboxyl group, a sulfo group, a phosphono group, phosphinic acid group, an alkoxycarbonyl group, an aryloxycarbonyl group, a carbamoyl group, an acylamino group, a sulfamoyl group, a sulfonylamino group, an alkylthio group, a cyano group, a ureido group or an ammonio group, ##STR2## wherein R.sub.1 represents an aryl group; and R.sub.2, R.sub.3, R.sub.4 and R.sub.5 each represents a hydrogen atom, an alkyl group, an aryl group, an alkoxyl group or an aryloxy group.
    • 描述了通过银盐扩散转移的图像形成方法,其包括使含有至少一个感光卤化银乳剂层的感光元件进行图像曝光,然后使用含有卤化银溶剂的碱处理组合物显影感光元件 将感光卤化银乳剂层的未曝光的卤化银的至少一部分转化为可转移的银络合盐,将至少一部分可转移的复合盐转移到含银沉淀的含核的图像接收层,以形成图像 银沉淀的含核影像接收层,以及在图像形成之后将含银析出核的图像接收层与感光元件分离以获得图像,其中图像是在至少一种由下式表示的化合物 (I)和至少一种化合物 通过下式(II)表示:其中R表示氢原子,未取代的烷基,未取代的烯基或-L2-A2; L1和L2各自表示亚烷基; A1和A2各自表示羧基,磺基,膦酰基,次膦酸基,烷氧基羰基,芳氧基羰基,氨基甲酰基,酰氨基,氨磺酰基,磺酰基氨基,烷硫基, 氰基,脲基或氨基,其中R 1表示芳基; R2,R3,R4和R5各自表示氢原子,烷基,芳基,烷氧基或芳氧基。
