Ascorbic acid developing compositions stabilized with sulfo compound and methods of use |
| abstract |
A black-and-white photographic developing composition has improved stability and is more compatible with the environment when discarded. The composition includes one or more ascorbic acid developing agents and a preservative (such as a sulfite) and is essentially free of hydroquinone and similar developing agents. Improved stability is provided using a sulfo-substituted organic compound as a stabilizing agent. Such compounds are either aliphatic sulfo compounds or hydroxy-free aromatic sulfo compounds. |
