Bleaching solution for processing photographic silver halide materials, especially color reversal films, comprises an iron propylenediaminetetraacetic acid and beta-alaninediacetic acid complex

摘要

Bleaching or bleaching/fixing solution (I) for processing photographic silver halide materials in which at least 65 mole% of the silver is in elemental form after development comprises an iron propylenediaminetetraacetic acid (PDTA) complex and an iron beta -alaninediacetic acid (ADA) complex in an amount of 0.045-0.25 mole/l. Independent claims are also included for the following: (1) a method for processing color reversal silver halide materials comprising a bleaching step in which a solution of type (I) is used; (2) a composition for producing, regenerating or rejuvenating (I), where the composition can consist of one or more components and comprises essentially all of the necessary chemicals.
