The activity of catalytic Ag nuclei formed by current has been studied. The Ag nuclei act as a latent image in an organic ion conductor consisted of benzotriazole (BZT) and silver benzotriazole (BZT-Ag), and are amplified by heat development under the presence of reducing agents. The efficiency of latent image formation is 10-3. The amplification ratio of the latent image is 106 which is comparable to that of AgCl.
