Abstract:
A silver halide color photographic light-sensitive material comprising at least one silver halide emulsion layer on a support, said at least one emulsion layer containing a magenta coupler represented by formula (M-2): where R1 represents a substituted or unsubstituted alkyl group, each of L1 and L2 independently represents a substituted or unsubstituted alkylene group, or a substituted or unsubstituted arylene group, R2 represents a halogen atom, nitro group, cyano group, â€”COR3, â€”COOR3, â€”CON(R4)R3, â€”N(R4)COOR3, â€”N(R4)CON(R5)R3, â€”CON (R4)SO2R3, or â€”N(R4)COR3, p is an integer from 1 to 5, wherein a plurality of R2â€²s may be the same or different if p is not less then 2, and each of R3, R4, and R5 independently represents a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group, R3 and R4 may be combined to form a ring, and the value or pKa at 25Â° C. of â€”NHSO2â€”which bonds to L2 and the phenyl group in a magenta coupler represented by formula (M-2) is not more than 12 in a solution of THF/H2O={fraction (6/4)}.
