ABSTRACT:
In a process for hardening gelatine containing photographic layers, in particular multilayered photographic films, using conventional hardeners and quick acting hardeners, the surface of a layer which contains gelatine and complex forming organic or inorganic salts is exposed to the action of an aqueous solution containing a wetting agent and a quick acting hardener, the quantity of water applied with the solution being calculated so that the layer or multilayered film undergoes swelling to a certain extend, and the degree of swelling is maintained for a period from 10 to 200 seconds, whereupon the layer or multilayered film is dried at a temperature below 30.degree.
