Abstract
Abstract A method of forming a color image which comprises processing a silver halide color photographic material comprising a reflective support having thereon at least one light-sensitive layer containing at least one coupler which forms a dye upon a coupling reaction with an oxidation product of an aromatic primary amine color developing agent and a silver halide emulsion which contains at least 80% by mol of silver chloride and substantially no silver iodide with a color developing solution which contains not more than 0.002 mol of a bromine ion per liter and substantially no benzyl alcohol for a development time of not more than 2 minutes and 30 seconds in the presence of at least one compound represented by the following formulae (I), (II), or (III): wherein R represents an alkyl group, an alkenyl group, or an aryl group; and X represents a hydrogen atom, an alkali metal atom, an ammonium group, or a precursor; wherein L represents a divalent connecting group; Rʹ represents a hydrogen atom, an alkyl group, an alkenyl group, or an aryl group; X has the same meaning as defined in formula (I); and n represents 0 or 1; and wherein Rʹ, X, L, and n each has the same meaning as defined in formula (II); R³ has the same meaning as defined for Rʹ; and Rʹ and R³ may be the same or different. A silver halide color photographic material which comprises a reflective support having thereon at least one light-sensitive layer containing at least one coupler which forms a dye upon a coupling reaction with an oxidation product of an aromatic primary amine color developing agent and a silver halide emulsion which contains at least 80% by mol of silver chloride and substantially no silver iodide, wherein the silver halide color photographic material has at least one layer coated on the support, which contains at least one compound represented by the following formulae (I), (II), or (III): wherein R represents an alkyl group, an alkenyl group, or an aryl group; and X represents a hydrogen atom, an alkali metal atom, an ammonium group or a precursor; wherein L represents a divalent connecting group; Rʹ represents a hydrogen atom, an alkyl group, an alkenyl group, or an aryl group; X has the same meaning as defined in formula (I); and n represents 0 or 1; and wherein Rʹ, X, L, and n each has the same meaning as defined in formula (II); R³ has the same meaning as defined for Rʹ; and Rʹ and R³ may be the same or different; and an amount of silver halide coated on the support, which is calculated in terms of silver, is not more than 0.78 g/m².
