ABSTRACT:
A method for forming an image by silver salt diffusion transfer is described, comprises processing an imagewise exposed photosensitive element provided with a layer of photosensitive silver halide emulsion on a support, and an image-receiving element provided with an image-receiving layer containing a silver-precipitating agent on a support, with an alkali processing composition in the presence of a silver halide solvent, to convert at least part of the unexposed silver halide in the emulsion layer into a transferable silver complex salt, to transfer at least part of said complex salt into the image-receiving layer, and to form an image in the image-receiving layer; the processing being carried out in the presence of at least one compound as described.
