Abstract
The present invention relates to a process for fixing silver iodide containing photographic material with a fixing bath. The bath contains, in addition to a compound capable of forming soluble silver complexes, at least one organic solvent, preferably N-methylpyrrolidone. The organic solvent increases the speed of dissolution of the silver iodide.
