发明名称 Photographic developing compositions and use thereof in the processing of photographic elements
摘要 Photographic developing compositions are provided that are free of dihydroxybenzene developing agents and are used in the processing of photographic elements. The developing compositions have a pH in the range of from 10.1 to 10.9 and comprise at least 0.17 moles per liter of an ascorbic acid developing agent, 0.3 to 0.5 moles per liter of a sulfite and 0.2 to 0.4 moles per liter of a carbonate buffer.
