Abstract

PURPOSE:To make a vinylsulfone hardener exhibit a sufficient hardening action without being accompanied by the loss in the photographic characteristics by specifying the pH values of gelatin applying liquid forming an emulsion layer of silver halide and an adjacent unphotosensitive layer. CONSTITUTION:A vinylsulfone hardener as specified by Formulas I to IV is added to a gelatine applying liquid for forming an emulsion layer of sliver halide, preferably, immediately prior to the application of the latter, and has its pH value adjusted to be lower than 6.2. A similar hardener of vinylsulfone is also added to a gelatine applying liquid for forming an unphotosensitive layer adjacent to that emulsion layer immediately prior to the application of the latter and has its pH value adjusted to be higher than 6.8.
