发明名称 Processing photographic materials and processing system therefor
摘要 A process for the processing of an imagewise exposed photographic material which has been subjected to development and bleach-fixing comprises a plurality of sequential washing steps and where a stain reducing agent is employed wherein the photographic material is contacted with an effective amount of the stain reducing agent in the wash liquid in a first washing step and the photographic material is subjected to a following washing step to remove the stain reducing agent. The process may employ a plurality of wash tanks in which the developed material is washed sequentially and the stain reducing agent is present in the wash liquid in a first wash tank and removed from the photographic material by the wash liquid in one or more following wash tanks. The temperature of wash liquids in the tanks is preferably within the range 40 to 70° C., preferably 45 to 65° C.The invention includes a photoprocessor system for the processing of photographic materials for example film or paper comprising: a development tank associated with a bleach-fix tank which is associated with a first of a plurality of wash tanks connected in series and wherein there is provided a reservoir for a stain reducing agent and means for supplying the stain reducing agent to the first wash tank.
