Abstract: A photographic material suited for the production of (an) azine dye image(s), and having at least one silver halide emulsion layer and/or a separate layer in water-permeable relationship with such an emulsion layer which contains:(1) a heterocyclic hydrazone compound,(2) a phenol, naphthol or active methylene coupler compound capable of forming on oxidative coupling with compound (1) an azine dye,(3) an electron transfer agent or ETA-compound capable of forming a positively charged semiquinone on oxidation with exposed silver halide,(4) a reducing agent capable of reducing the thus-formed semiquinone in acidic medium, and having in the pH range of 2-5, a polarographic half-wave potential (E 1/2) which is at least 40 mV more negative (according to the European Convention) than the polarographic half-wave potential of the ETA-compound in the same pH range, said material being suited for processing with a simple aqueous alkaline liquid, and(5) an acidic medium.

Abstract: An improved method for bleaching color photosensitive materials with a persulfate is provided. This method is free of offensive odors, can bleach efficiently color photosensitive materials containing a large amount of silver by using a persulfate, and can effectively bleach color photosensitive materials having colloidal silver layers by using a persulfate. The color photosensitive material used in the present invention contains at least one of the compounds represented by the formula I, salts thereof and precursors thereof: ##STR1## where R.sup.1 and R.sup.2 each independently represents a hydrogen atom, or an aliphatic residue and R.sup.1 and R.sup.2 may form a ring together with the N atom; R.sup.3 represents --R.sup.4 -- or --R.sup.4 --S, said --R.sup.4 -- being a divalent aliphatic residue; and X represents a divalent heterocyclic ring residue containing at least one atom selected from the group consisting of a nitrogen atom, an oxygen atom, and a sulfur atom.
