Abstract

Abstract PURPOSE:To prevent the fading of a developed color image by carrying out stabilization with a specified dye stabilizing soln. in the final stage of color processing. CONSTITUTION:Stabilization is carried out with a dye stabilizing soln. of 3.0-9.0pH contg. a soluble iron salt and an antifungal agent in a stage after a bleach-fixing or fixing stage. Washing is not practically carried out. An inorg. ferrous or ferric salt, iron carboxylate or an iron complex salt may be used as the soluble iron salt. In case of <3.0 or >9.0pH or the stabilizing soln., the dye fading preventing effect of the soluble iron salt is weakened, so the soln. is kept at 3.0-9.0pH. The antifungal agent is added so as to maintain the pH of the stabilizing soln. When the stabilizing soln. is used, the fading of a developed color image can be inhibited without softening the gelatin film and the amount of washing water required can be reduced.
