Abstract: A non-hydroquinone and non-alkali metal hydroxide containing developer composition for radiographic materials and a method of use thereof are provided. The developer composition comprises a developer selected from the group consisting of ascorbic acid and sugar-type derivatives thereof, stereoisomers and diastereoisomers of ascorbic acid and its sugar-type derivatives, their salts and mixtures thereof, together with a sulfite, a 3-pyrazolidone compound, and an anti-swelling agent selected from the group consisting of sodium sulfate, glutaraldehyde or mixtures thereof, said composition having a pH of from 9.5 to 10.6, and said developer being present in an amount of at least about 15 grams, said sulfite being present in an amount of from 2 to 50 grams, said swelling control agent being present in an amount of from 35 to 90 grams, and water to 1.0 liter.

Abstract: An environmentally-safe, non-toxic non-hydroquinone and non-alkali metal hydroxide containing photographic developer composition is provided comprising a developer selected from the group consisting of 2-keto gluconic acid and derivatives thereof, together with a sulfite, an alkali metal carbonate, and a 3-pyrzaolidone developer compound.
