在加工彩色正性照相材料时,由于彩显液不断地被带进漂白液或漂一定液中,而漂白液又都是氧化剂,因此彩色显影剂进入漂白液后立即被氧化,其氧化产物与乳剂层中的成色剂起偶合反应,导致并形成了不应有的彩色“灰雾”。 When processing color positive photographic materials, the color developing agent is oxidized immediately after it enters the bleaching solution because the color developing liquid is continuously brought into the bleaching solution or the bleaching solution which are both oxidants. The oxidation products of the color developing agent The coupler in the emulsion layer acts as a coupling reaction, resulting in and forming an undesirable color “fog.”
