摘要：
Black-and-white elements, such as radiographic films, can be processed in roomlight using a developing/fixing monobath composition that also includes a water-soluble colorant, such as a water-soluble "yellow" dye, that provides safelight conditions in the processing composition. The processing method is carried out quickly, that is within 120 seconds. The colorant has a maximum absorption wavelength of from about 350 to about 500 nm, and is transparent in solution.
