Weakly alkaline ascorbic acid developing composition, processing kit and method using same |
| abstract |
A black-and-white developing composition includes as ascorbic acid developing agent, an auxiliary super-additive developing agent, borate buffer and a preservative. The composition pH is from 7 but less than 9. The composition can be formulated from two separately packaged parts that may be in dry or liquid form. The borate buffer is present to maintain the desired pH, and the two developing agents are present in desired molar ratios for optimal developing activity. Improved photographic properties are obtained while avoiding the use of environmentally unfriendly dihydroxybenzenes. |
