Abstract
A stabilizing bath which provides reduced stain and enhanced dye stability for photographic color elements which are processed therein is comprised of a dye stabilizing agent and an alkanolamine. The stabilizing bath is used as a final processing bath which follows treatment of the element in a fixing or bleach-fixing bath containing a thiosulfate fixing agent. The alkanolamine functions to prevent the precipitation of sulfur resulting from carryover of the thiosulfate fixing agent into the stabilizing bath.
Claims18
An aqueous photographic stabilizing bath for use in the color processing of photographic elements, said bath containing a dye stabilizing agent and an alkanolamine, said alkanolamine being present in an amount sufficient to inhibit sulfurization of said stabilizing bath resulting from carry-in of a thiosulfate fixing agent.
An aqueous photographic stabilizing bath for use in the color processing of photographic elements, said bath containing formaldehyde in an amount sufficient to improve dye stability of said photographic element and triethanolamine in an amount sufficient to inhibit sulfurization of said stabilizing bath resulting from carry-in of a thiosulfate fixing agent.
In a method for processing a silver halide photographic color element comprising the steps of treating said element in succession with a color developing solution, a bleach-fixing solution or separate bleaching and fixing solutions, and a stabilizing solution;
- said fixing or bleach-fixing solution containing a thiosulfate fixing agent which is carried by said element into said stabilizing solution;
- the improvement wherein said stabilizing solution contains a dye stabilizing agent and a sufficient amount of an alkanolamine to retard decomposition of said thiosulfate and resulting sulfurization of said stabilizing solution.
In a method for processing a silver halide photographic color element comprising the steps of treating said element in succession with a color developing solution, a bleach-fixing solution or separate bleaching and fixing solutions, and a stabilizing solution;
- said fixing or bleach-fixing solution containing a thiosulfate fixing agent which is carried by said element into said stabilizing solution;
- the improvement wherein said stabilizing solution contains formaldehyde in an amount sufficient to serve as a dye stabilizing agent and triethanolamine in an amount sufficient to retard decomposition of said thiosulfate and resulting sulfurization of said stabilizing solution.
