摘要： A method for forming images by silver salt diffusion transfer comprising
imagewise exposing a light-sensitive element comprising a light-sensitive silver halide emulsion layer,
developing the light-sensitive element in the presence of a silver halide solvent using an alkaline processing composition to turn at least a part of unexposed silver halide of the light-sensitive silver halide emulsion layer into a transfer silver halide complex salt, and
transferring at least a part of the silver halide complex salt to an image receiving layer comprising a silver precipitating agent to form images on the image receiving layer,
wherein at least one compound represented by formula (I) is added to at least one of the light-sensitive element, an image receiving element comprising the image receiving layer, and the processing composition in an amount of at least 1 x 10- 6 and less than 1 x 10- 2 mol based on one mol of silver applied per unit area (m 2 ):
wherein Q represents an atomic group for forming a quinone ring; R represents a monovalent group which may be substituted or unsubstituted; and n is an integer of 0 to 4, whereby the maximum density can be increased for a short time.摘要翻译： 通过银盐扩散转印形成图像的方法包括使包含感光卤化银乳剂层的感光元件成像曝光，使用碱性处理组合物在卤化银溶剂的存在下显影感光元件， 将感光卤化银乳剂层的未曝光卤化银的至少一部分转移到转移卤化银配合盐中，并将至少一部分卤化银配盐转移到包含银沉淀剂的图像接收层上以形成图像 图像接收层，其中至少一种由式（I）表示的化合物添加到至少一种感光元件，包含图像接收层的图像接收元件和至少1×10 基于每单位面积（m 2）施加的一摩尔银，小于1×10 -3摩尔，小于1×10 -2摩尔：其中Q表示原子团 形成醌环; R表示可以被取代或未取代的一价基团; n为0〜4的整数，能够在短时间内增加最大密度。
