A desensitizing solution and process for using the solution are disclosed to desensitize a diazo photosensitive printing plate after development. The solution comprises a water soluble desensitizing agent capable of reacting with any residual photosensitive diazo on the developed plate to render the diazo incapable of forming an oleophilic substance and a filming agent selected from water soluble aliphatic polyols have less than eight carbon units, the acid derived monoesters of these polyols, and the alkali metal salts of the monoesters.
