  • Processing radiographic films with low developer replenishment using an alkaline replenishing solution
    Patent number: 5652086
    Abstract: Radiographic films can be processed using conventional developing agents, either in the films or in solution. The films also include from about 0.02 to about 1 mg/dm.sup.2 of thialkylene bis(ammonium salt). The solution used for development is replenished at a low rate with a chemical base as the sole developer replenishing agent. The chemical base maintains developer composition pH at from about 9 to about 11 and enables processing of films without the use of conventional developer replenishing solutions or replenishment rates.
