Abstract: 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 &bgr;-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.

Abstract: A one-part, multi-phase colour developer concentrate having an aqueous phase and an organic phase, wherein the organic phase is constituted by a carboxylic acid amide or urea derivative which is liquid at room temperature and the concentrate contains at least one compound of the formulae (I), (II) or (III) as antioxidant: in which R1 means alkyl, R2 means alkyl or aryl and n means 0 or 1 and at least one of the residues R1 and R2 contains at least one —OH, —COOH or —SO3H group; in which R3 means an alkyl or acyl group; in which R4 means an alkylene group optionally interrupted by O atoms and m means a number of at least 2, is in particular suitable for the production of a colour developer solution for silver halide materials having an elevated AgCl content.
