SILVER HALIDE PHOTOGRAPHIC SENSITIVE MATERIAL

PURPOSE:To stably obtain an action of hardening gelatin and photographic characteristics by incorporating at least one kind of alkaline agent in an aldehyde type hardener. CONSTITUTION:At least one kind of alkaline agent is incorporated in the aldehyde type hardener contained in at least one of hydrophilic colloidal layer of the photographic sensitive material formed on a support. As this alkaline agent to be used for the hardener stabilizer, usually used alkalis, that is, aqueous solutions of alkali metal and ammonium hydroxides and salts, such as sodium or potassium hydroxide, sodium or potassium carbonate, sodium sulfate or sodium sulfite, ammonium carbonate sodium phosphate, are used, and they are not especially limited, so long as it is alkaline, thus permitting the gelatin hardening action and the photographic characteristics to be both stably maintained.
