Abstract
A black-and-white silver halide developing solution and a silver halide solution physical developing solution are used in sequence to provide electrically-conductive film elements from conductive film element precursors that contain photosensitive silver halide emulsions on one or both supporting sides of a transparent substrate. The two developing solutions have unique combinations of developing agents and other essential components to provide complete development of imagewise exposed silver halide to form highly electrically-conductive silver metal in predetermined patterns.
