Abstract

Abstract A method for forming an image of a silver halide color photograph, which comprises processing a silver halide color photographic material with a color developing solution containing at least one aromatic primary amine color developing agent, comprises: processing a silver halide color photographic material having at least one layer containing a compound represented by formula (S) and a silver halide emulsion comprising at least 80 mol % of silver chloride with a color developing solution containing chlorine ion in an amount of 3.5×10 -2 to 1.5×10 -1 mol/l and bromine ion in an amount of 3.0×10 -5 to 1.0×10 -3 mol/l: ##STR1## wherein Z 1 represents a nitrogen atom, an oxygen atom, a sulfur atom or a selenium atom; Z 2 represents an oxygen atom, a sulfur atom or a selenium atom; L 1 , L 2 , L 3 , L 4 and L 5 each represents a methine group which may be optionally substituted or may be combined together with another methine group to form a ring; R 1 and R 2 may be the same or different groups and each is an alkyl group; R 1 and L 1 or R 2 and R 5 may be combined together to form a five-membered or six-membered ring; V 1 , V 2 , V 3 , V 4 , V 5 , V 6 , V 7 and V 8 each represents a hydrogen atom, a halogen atom, an alkyl group, an acyl group, an acyloxy group, an alkoxycarbonyl group, a carbamoyl group, a sulfamoyl group, a carboxyl group, a cyano group, a hydroxyl group, an amino group, an acylamino group, an alkoxy group, an alkylthio group, an alkylsulfonyl group, a sulfo group, an aryloxy group or an aryl group, and among V 1 to V 8 , two groups attached to adjacent carbon atoms may be combined together to form a condensed ring; (X 1 )n 1 represents a counter ion; and n 1 is a value required for the neutralization of 0 or more electric charges.
