    摘要: A photographic developer containing hydroquinone, an auxiliary developer such as phenidone, and high sulfite is formulated using an organic base such as diethanolamine. This is useful for processing litho film in rapid access machine processors to produce high contrast line and half-tone dot images from films processed therein.
