Abstract
A process for inhibiting the formation of an unwanted precipitate comprising [H.sub.2-n TMT]Na.sub.n [HNR.sub.3 ] during the precipitation of silver mercapto-s-triazine (AgTMT) from a silver containing photoprocessing solution, comprising the steps of: (a) providing a base solution; (b) providing a reagent solution containing mercapto-s-triazine (TMT), or a water soluble salt thereof; (c) mixing the TMT reagent solution with the photoprocessing solution; and (d) adding sufficent base to increase the pH of the mixture of the TMT reagent and photoprocessing solutions above the pH of the mixture before addition of base, and the base is mixed: (i) directly to the photoprocessing solution before mixing TMT reagent with the photoprocessing solution; or (ii) with the photoprocessing solution concurrently with TMT reagent; or (iii) immediately after the point TMT reagent begins mixing with the photoprocessing solution.
