Color photographic light-sensitive material

A method of forming a color image comprising developing an imagewise exposed silver halide color photographic light-sensitive material comprising a support having coated thereon at least one silver halide emulsion layer, the color photographic light-sensitive material having at least one layer containing at least one 2-equivalent magenta coupler of the 5-pyrazolone type represented by the following general formula (I):

• ##STR29## wherein W represents a phenyl group substituted with at least one substituent selected from the group consisting of a halogen atom, an alkyl group, an alkoxy group, an alkoxycarbonyl group and a cyano group;
• Y represents an acylamino group or an anilino group;
• and Z represents a group capable of being released upon coupling, and at least one compound represented by the following general formula (II):
• ##STR30## wherein R.sup.1 and R.sup.2, which may be the same or different, each represents a hydrogen atom, an alkyl group or an aryl group, provided that both R.sup.1 and R.sup.2 do not represent hydrogen atoms at the same time;
• Z.sup.1 represents a methine group, a substituted methine group or the group --N.dbd.;
• and Q represents an atomic group which contains a nitrogen atom, a sulfur atom or an oxygen atom and is necessary to form a 5-membered or a 6-membered heterocyclic ring together with the group ##STR31## with an aqueous alkaline solution containing a color developing agent;
• wherein the group capable of being released upon coupling represented by Z is an aryloxy group, an alkoxy group, a heterocyclic oxy group, a silyoxy group, a phosphonoxy group, an alkylthio group, an arylthio group, a heterocyclic thio group, an acylthio group, a thiocyano group, an aminothiocarbonylthio group, an acylamino group, a suflonamido group, an alkoxycarbonylamino group, an aryloxycarbonylamino group or a nitrogen-containing heterocyclic group which is connected to the active position of the pyrazolone ring through the nitrogen atom;
• and
• wherein the aryl group represented by R.sup.1 or R.sup.2 is an aryl group having from 6 to 38 carbon atoms which may be substituted with a halogen atom, an aryl group, a heterocyclic group, a cyano group, an alkoxy group, an aryloxy group, an acylamino group, an imido group, an anilino group, an alkylamino group, a heterocyclic amino group, a ureido group, a sulfamoylamino group, an alkylthio group, an arylthio group, a heterocyclic thio group, an alkoxycarbonylamino group, an aryloxycarbonylamino group, a sulfonamido group, a carbamoyl group, a sulfamoyl group, a sulfonyl group, a sulfinyl group, an acyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a phosphonyl group, an imino group, a cyanothio group, an acyloxy group, a carbamoyloxy group, a silyloxy group, a sulfonyloxy group, a heterocyclic oxy group, a hydroxy group or a nitro group.
