PURPOSE:To prevent generation of a bacteria or a fungi in a water-washing tank, even in case of reducing an used amount of the washing water by incorporating 10,10'-oxybisphenoxyarsine to said processing solution used in the water- washing step and/or the stabilizing step. CONSTITUTION:10,10'-Oxybisphenoxyarsine which is dissolved in a solvent is incorporated to the water-washing or stabilizing processing solution in color- processing of the titled material which is exposed, thereby preventing effectively the generation of the bacteria and fungi in the water-washing tank and/or the stabilizing tank, and the generation of stain in the titled material after processing. |
