摘　　要：本文论述了彩色感光材料如:彩色相纸、彩色负片的冲洗加工过程中,彩色显影液被漂定液、漂白液或定影液污染后对彩色感光材料照相性能的影响;实践证明,即使仅仅在彩色显影液中混入微量的漂定液、漂白液或定影液,也会产生严重的影响,表现在特性曲线的主要指标上,如:灰雾、低密度级、高密度级、反差、黑块等。因此,一旦发现这种污染,应立即彻底清洗冲洗加工系统并更新彩色显影液,同时应查找原因,杜绝事故。This paper elucidates the effects of color developer stained by bleach-fixer, bleaching bath or fixer during processing on the photographic characteristics of color photo-materials e.g. color paper and film. Practice showed that even minim quantity of staining can affect very seriously main parameters of the characteristic curve namely： the fog, low density step, high density step, contrast and maximum density. So, once that staining happened, the processing system should be thoroughly cleaned and the color developer renewed; besides, the causes should be unveiled to prevent similar accidents.
