发明名称 Bleach bath
摘要 A bleach or bleach/fixing solution for processing photographic silver halide materials which, relative to the silver halide content of the unprocessed material, exhibit prior to the bleaching step a content of silver arising from development of at least 65 mol %, in particular for processing color reversal materials, characterized in that the solution contains at least one iron complex of propylenediaminetetraacetic acid or of beta-alaninediacetic acid or a mixture of these complexes and the total concentration of the stated iron complexes in the solution is at least 0.045 and at most 0.25 mol/l and a process for processing, in which such a solution is used, is characterized by a small introduced quantity of iron complexes, a low residual silver content, a low bleaching fog value, elevated resistance to precipitation and in that the bleach solution may be rejuvenated.
