摘要：Dissolution of silver halides and diffusion of silver complexes in diffusion transfer precesses were investigated using an electrochemical model, in which a silver plate coated with AgCl emulsion was employed as a working electrode. The silver potential of the solution including thiosulfate as a fixing agent was more positive than that with thiocyanate, especially in the initial stage of the process. It was concluded that species reaching the development center were Ag (S₂O₃) ^- and Ag (SCN) ₄^3-in the solution including thiosulfate and thiocyanate, respectively. The diffusion of thiosulfate ion and thiosulfate complexes was accelerated by additon of sulfite, whereas that of thiocyanate was little affected.
