ABSTRACT:
A method of forming a silver salt diffusion transfer image comprises developing an imagewise exposed photosensitive silver halide emulsion layer with a developing agent and a silver halide solvent in the presence of an alkali to thereby convert at least a portion of unexpected silver halide in said emulsion layer to a diffusible silver complex salt and transferring at least a portion of said silver complex salt into a silver precipitating agent-containing image receivin- layer to form an image in said image receiving layer. In the above method said image is formed in the presence of a compound selected from the group consisting of compounds of the general formulae (I), (II) and (III): ##STR1##
