PURPOSE:To store a developing solution for a long term stably without deteriorating the capacity of the solution, by rendering an oxygen absorber present together in the vessel containing the developing solution. CONSTITUTION:An oxygen absorber is hung in the closely sealed vessel containing a developing solution for use in a black and white photographic paper or film or a color negative film. As said oxygen absorber, a composition consisting chiefly of an iron-carbon alloy, such as that of >=0.5% graphite content, preferably >=1.7% is used. |
