A silver halide color photographic material which comprises a support having at least one silver halide color photographic emulsion layer coated thereon and containing at least one compound represented by the following general formula (I) and at least one compound represented by the following general formula (II) in at least one of hydrophilic layers provided on the support: Image (I) wherein each of R1 and R2 represents -COOR5 or Image ; each of R3 and R4 represents hydrogen or an alkyl group; each of R5 and R6 represents a hydrogen atom, an unsubstituted alkyl group, an aryl group or R5 and R6 together form a 5- or 6-membered ring; each of Q1 and Q2 represents an aryl group; each of X1 and X2 represents a divalent bonding group or a bond; each of Y1 and Y2 represents a sulfonic acid group or a carboxylic acid group; each of L1, L2 and L3 represents a methine group; each of m1 and m2 represents 1 or 2; n represents 0, 1 or 2; each of p1 and p2 represents 0, 1, 2, 3 or 4; and each of s1 and s2 represents 1 or 2; and Image (II) wherein Y3 represents -NHCO- or -CONH-; R8 represents an aliphatic group, an aromatic group, a heterocyclic group or an aryl amino group which may be substituted; X3 represents hydrogen, a halogen atom, an alkoxy group or an acylamino group; R7 represents a alkyl group (containing two or more carbon atoms), an acyl amino group or a nonmetallic atomic group necesasry to form a 5 to 7 membered ring by the combination of X3 and R7; and Z represents a hydrogen atom or a group which can be released by coupling with an oxidized color developing agent. The materials give stable color images in long storage, high sharpness, high sensitivity and low fogging property because of using new dyes and couplers.
