Abstract

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: ##STR1## wherein: Y represents --NHCO-- or --CONH--; PA1 R.sub.1 represents an aliphatic group, an aromatic group, a heterocyclic group or an amino group; PA1 X represents a hydrogen atom, a halogen atom, an aliphatic group, an alkoxy group or an acylamino group; PA1 R.sub.2 represents an alkyl group or an acylamino group or, when bound to X, non-metallic atoms forming a 5- to 7-membered ring; PA1 Z represents a hydrogen atom or a group capable of being eliminat…
