Processing of low silver black-and-white photographic elements with environmentally sensitive compositions

摘要

Low silver black-and-white photographic elements, such as radiographic films, can be processed quickly using black-and-white developing and fixing compositions having reduced photoprocessing activity. The entire process is fairly rapid and effective despite the lowered concentrations of photographic developing and fixing agents. The processing compositions are more environmentally friendly because the conventional hydroquinone is replaced with an ascorbic acid developing agent. In addition, the processing compositions are free of ammonium ions.
