Abstract: A silver halide color photographic material is described, which comprises a support having thereon at least one blue-sensitive silver halide emulsion layer, at least one green-sensitive silver halide emulsion layer, at least one red-sensitive silver halide emulsion layer and at least one light-insensitive layer, wherein one or more of the above layers contain at least one compound represented by formula (A-I), (A-II), (A-III), (A-IV) or (A-V) and one or more of the above layers contain at least one compound represented by formula (H):
     
       
 wherein R a1  represents an alkyl group, an alkenyl group, an aryl group, an acyl group, an alkylsulfonyl group, an arylsulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, a carbamoyl group, a sulfamoyl group, an alkoxycarbonyl group, or an aryloxycarbonyl group; R a2  represents a hydrogen atom or a substituent described for R a1 , provided that when R a1  represents an alkyl group, an alkenyl group or an aryl group, R a2  represents an acyl group, an alkylsulfonyl group, an arylsulfonyl group, an alkylsulfinyl group, an arylsulfinyl group, a carbamoyl group, a sulfamoyl group, an alkoxycarbonyl group or an aryloxycarbonyl group, and R a1  and R a2  may be bonded with each other to form a 5- to 7-membered ring; X represents a heterocyclic group; R b1  represents an alkyl group, an alkenyl group or an aryl group, and X and R b1  may be bonded with each other to form a 5- to 7-membered ring; Y represents a nonmetallic atomic group necessary to form a 5-membered ring together with an -N=C- group, Y further represents a nonmetallic atomic group necessary to form a 6-membered ring together with an -N=C- group, and the terminal of Y bonded to the carbon atom of an -N=C- group represents a group selected from the group consisting of -N(R c1 )-, -C(R c2 )(R c3 )-, -C(R c4 )=, -O- and -S- (bonded to the carbon atom of an -N=C- group at the left side of each group); R c1 , R c2 , R c3  and R c4  each represents a hydrogen atom or a substituent; R d1  and R d2 , which may be the same or different, each represents an alkyl group or an aryl group, provided that when R d1  and R d2  represent unsubstituted alkyl groups at the same time and yet R d1  and R d2  represent the same groups, R d1  and R d2  represent an alkyl group having 8 or more carbon atoms; R e1  and R e2 , which may be the same or different, each represents a hydroxylamino group, a hydroxyl group, an amino group, an alkylamino group, an arylamino group, an alkoxyl group, an aryloxy group, an alkylthio group, an arylthio group, an alkyl group or an aryl group, provided that R e1  and R e2  do not represent -NHR e3  (where R e3  represents an alkyl group or an aryl group) at the same time;
       
 wherein X represents -N(R 1 )R 3 , where R 1  represents a hydrogen atom, an aliphatic group, an aromatic group or a heterocyclic group, and R 3  represents a hydrogen atom or a group removed off under an alkaline condition; R 2  represents a hydrogen atom, an aliphatic group, an aromatic group, a heterocyclic group, a cyano group, a nitro group or a hydrazino group; X and R 2  may be linked to form a ring; R 5  represents a hydrogen atom, an alkyl group or a group removed off under an alkaline condition; two or more of formula (H) may be bonded at the R 1 , R 2  or R 5  part to form an oligomer or polymer; G represents -CO-, -COCO-, -SO 2 -, -SO-, -CON(R 6 )-, -COO-, -COCON(R 7 )-, -COCOO-, -PO(R 8 ), -PO(R 8 )O-, -CS- or an iminomethylene group, where R 6  and R 7  represent a hydrogen atom, an alkyl group or an aryl group, and R 8  represents an alkyl group, an aryl group, an alkoxyl group or an aryloxy group; and m is 0, 1 or 2, and when m is 2, G may be the same or different.
