Abstract

Abstract A method for processing a silver halide color photosensitive material which comprises processing a silver halide color photosensitive material containing at least one 4-mercapto-5-pyrazolone type magenta coupler represented by formula (I) ##STR1## wherein W represents an aryl group; X represents an alkyl group, an aryl group or a heterocyclic ring group; and Y represents an acylamino group, a ureido group, or an anilino group; with a color developer containing at least one compound selected from a compound represented by formula (II) ##STR2## wherein R represents a lower alkyl group, and M 1 and M 2 , which can be the same or different, each represents a hydrogen atom, and an alkali metal atom, or an ammonium group; a compound represented by formula (III) ##STR3## wherein M 3 , M 4 , M 5 , M 6 and M 7 , which can be the same or different, each represents a hydrogen atom, an alkali metal atom, or an ammonium group, and n represents an integer of 1 or 2; and an aminopolyphosphonic acid, and a phosphonocarboxylic acid in a concentration greater than 5.0×10 -3 mol/liter.
