| description | A black-and-white photographic developing composition or developing kit includes an ascorbic acid developing agent and is essentially free of hydroquinone and similar developing agents. The developing composition further includes a water-miscible hydroxy-containing organic solvent having a molecular weight of from about 50 to about 200. The weight ratio of the organic solvent to water is from about 0.1:1 to about 8:1. |
