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.

摘要： Black-and-white elements, such as radiographic films, can be processed in roomlight because the developing composition includes a water-soluble colorant. Such colorants are water-soluble dyes that have a maximum absorption wavelength of from about 350 to about 500 nm. Processing is carried out by processing the exposed element using a two-stage process in the same processing container. In the first stage, development is initiated with an opaque developing composition having a pH of from about 10 to about 12.5, and comprising an appropriate black-and-white developing agent, a yellow colorant, and a sulfite. After an appropriate time, a fixing agent (other than a sulfite) is introduced into the processing container to begin simultaneous development and fixing. The entire process in quite rapid, that is less than 90 seconds.
