发明名称 Image-forming process comprising bleaching at low pH a material comprising a cyan coupler and hydroquinone
摘要 An image-forming process, which comprises subjecting a multilayer silver halide color photographic material containing, in an oil droplet dispersion in a light-sensitive layer provided on a support, at least one of the diffusion-resistant oil-soluble couplers capable of coupling with an oxidation product of an aromatic primary amine developing agent to form a substantially non-diffusible cyan dye represented by the following formula (I) and at least one member selected from the compounds represented by the following formulae (II) and (III), to imagewise exposure and color development, and then processing the multilayer silver halide photographic material with a bleaching or bleach-fixing solution having a pH of 6.3 or less: <IMAGE> (I) <IMAGE> (II) <IMAGE> (III) wherein: Y represents -NHCO- or -CONH-; R1 represents an aliphatic group, an aromatic group, a heterocyclic group or an amino group; X represents a hydrogen atom, a halogen atom, an aliphatic group, an alkoxy group or an acylamino group; R2 represents an alkyl group or an acylamino group or, when bound to X, non-metallic atoms forming a 5- to 7-membered ring; Z represents a hydrogen atom or a group capable of being eliminated upon coupling with an oxidation product of a developing agent; and R3, R4, R5, and R6 each represents a hydrogen atom, a chain, cyclic or branched alkyl or alkylthio group, provided that R3 and R4, or R5 and R6, do not represent hydrogen atoms at the same time and that, when they represent alkyl groups, those which are bound to the benzene ring via a tertiary carbon atom are excluded.
