Abstract:
A silver halide color photographic lightsensitive material comprising, on a support, at least one silver halide emulsion layer, wherein the silver halide color photographic lightsensitive material comprises:at least one magenta coupler represented by a general formula (MC-I): wherein each of R31 and R32 independently represents a hydrogen atom, a substituted or unsubstituted alkyl group, or a substituted or unsubstituted aryl group; and at least one compound selected from the group consisting of compounds represented by general formula (TS-I-&agr;), general formula (TS-II) and general formula (TS-III): in the formula (TS-I-&agr;), each of R1a and R1b independently represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted acyl group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted aryloxycarbonyl group, a substituted or unsubstituted alkylsulfonyl group, a substituted or unsubstituted arylsulfonyl group, a substituted or unsubstituted phosphino group, a substituted or unsubstituted phosphinyl group or a group of the formula â€”SiR21R22R23, wherein each of R21, R22 and R23 independently represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkenyloxy group or a substituted or unsubstituted aryloxy group; each of â€”X1aâ€” and â€”X1bâ€” independently represents â€”Oâ€”, â€”Sâ€” or â€”N(R24)â€”, wherein R24 has the same meaning as R1a; and R2, R3, R5 and R6 may be identical with or different from each other, and each thereof represents a hydrogen atom or a substituent, provided that R1a and R2, or R24 and R6, or R1a and R24, may be bonded with each other to thereby form a 5 to 7 membered ring, provided that R2 and R3, or R3 and R1b, or R1b and R5, or R5 and R6, may be bonded with each other to thereby form a 5 to 7 membered ring, spiro ring or bicyclo ring, and provided that R1a, R2, R3, R1b, R5, R6 and R24 are not simultaneously hydrogen atoms; in the formula (TS-II), each of R11, R12, R13 and R14 independently represents a hydrogen atom, a substituted or unsubstituted alkyl group or a substituted or unsubstituted alkenyl group, provided that R11 and R12, or R13 and R14, may be bonded with each other to thereby form a 5 to 7 membered ring; X2 represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted alkenyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted alkenyloxy group, a substituted or unsubstituted alkyloxycarbonyl group, a substituted or unsubstituted alkenyloxycarbonyl group, a substituted or unsubstituted aryloxycarbonyl group, a substituted or unsubstituted acyl group, a substituted or unsubstituted acyloxy group, a substituted or unsubstituted alkyloxycarbonyloxy group, a substituted or unsubstituted alkenyloxycarbonyloxy group, a substituted or unsubstituted aryloxycarbonyloxy group, a substituted or unsubstituted alkylsulfonyl, a substituted or unsubstituted alkenylsulfonyl group, a substituted or unsubstituted arylsulfonyl group, a substituted or unsubstituted alkylsulfinyl group, a substituted or unsubstituted alkenylsulfinyl group, a substituted or unsubstituted arylsulfinyl group, a substituted or unsubstituted sulfamoyl group, a substituted or unsubstituted carbamoyl group, a hydroxyl group or an oxyl group; and X3 represents a group of nonmetallic atoms required to form a 5 to 7 membered ring; and in the formula (TS-III), each of R21 and R22 independently has the same meaning as R1a; X4 represents a substituted or unsubstituted alkyl group or a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, â€”COâ€”R123, â€”COâ€”Oâ€”R123 or â€”COâ€”NR124(R125), wherein R123 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group or a substituted or unsubstituted heterocyclic group, and each of R124 and R125 independently represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted amino group, or a substituted or unsubstituted alkoxy group.
