Abstract:
A method of processing comprising:bleaching or bleach-fixing an imagewise exposed and developed silver halide color photographic element that has at least one layer containing a cyan dye, with a bleaching or bleach-fixing composition to achieve accelerated leuco cyan dye recovery within 180 seconds, said bleaching or bleach-fixing composition comprising a mixture of:one or more ferric complexes of an aminopolycarboxylic acid that is propylenediaminetetraacetic acid, methyliminodiacetic acid, beta-alaninediacetic acid or ethylenediamine disuccinic acid, the one or more complexes being present as the sole bleaching agent or agents present in an amount to provide ferric ion at from about 0.005 to about 0.5 mol/l, and the molar ratio of said aminopolycarboxylic acid to ferric ion is from about 1:1 to about 5:1, andsubstantially in an uncomplexed form, an aromatic carboxylic acid that is 2-pyridinecarboxylic acid, 2,3-pyridinedicarboxylic acid or 2,6-pyridinedicarboxylic acid,said molar ratio of the uncomplexed aromatic carboxylic acid to the ferric ion in said bleaching agent being from 0.02:1 to 0.8:1.
