Abstract:
A silver halide color photographic lightsensitive material comprising at least one layer on a support, wherein the at least one layer contains a coupler represented by formula (I) below: whereinX represents a member selected from the group consisting of a hydrogen atom, halogen atom, 1- to 32-carbon alkoxy group, 6- to 32-carbon aryloxy group, 1- to 32-carbon alkylthio group, 6- to 32-carbon arylthio group, 2- to 32-carbon heterocyclic thio group, 2- to 32-carbon alkoxycarbonyloxy group, 7- to 32-carbon aryloxycarbonyloxy group, 1- to 32-carbon carbamoyloxy group, 3- to 32-carbon heterocyclic carbonyloxy group, 2- to 30-carbon alkylcarbonyloxy group, 7- to 30-carbon arylcarbonyloxy group, and 2- to 32-carbon, 5- or 6-membered nitrogen-containing heterocyclic group that bonds to the coupling active position with a nitrogen atom; each of R1 and R2 represents an electron-attracting group having a Hammett's substituent constant &sgr;p value of not less than 0.20, the sum of the &sgr;p values of R1 and R2 being not less than 0.65; R3 represents a member selected from the group consisting of a substituted or nonsubstituted alkyl group, substituted or nonsubstituted alkenyl group, substituted or nonsubstituted alkynyl group, substituted or nonsubstituted cycloalkyl group, substituted or nonsubstituted cycloalkenyl group, substituted or nonsubstituted aryl group, and substituted or nonsubstituted heterocyclic group, and R4 represents a member selected from the group consisting of a hydrogen atom, substituted or nonsubstituted alkyl group, substituted or nonsubstituted alkenyl group, substituted or nonsubstituted alkynyl group, substituted or nonsubstituted cycloalkyl group, substituted or nonsubstituted cycloalkenyl group, substituted or nonsubstituted aryl group, substituted or nonsubstituted acyl group, substituted or nonsubstituted alkoxycarbonyl group, substituted or nonsubstituted aryloxycarbonyl group, and substituted or nonsubstituted carbamoyl group, or alternatively, R3 and R4 may bond together to form a ring structure; and each of R11 to R15 independently represents a hydrogen atom or a substituent, and at least one of R11 to R15 represents â€”(L1)â€”(L2)nâ€”R, wherein L1 represents a member selected from the group consisting of â€”CONHâ€”, â€”NHCONHâ€”, â€”NHCOOâ€”, â€”NHCOâ€”, â€”OCONHâ€”, â€”NHâ€”, â€”NRXâ€”, â€”COOâ€”, â€”OCOâ€”, â€”COâ€”, â€”Oâ€”, â€”Sâ€”, â€”SO2â€”, â€”NHSO2â€”, â€”SO2NHâ€”, and â€”CH2â€” (wherein the left side of each group binds to the benzene ring of formula (I), and RX represents an alkyl group), L2 represents â€”CH2CH2Oâ€” or â€”CH2CONHâ€” (wherein the left side of each group binds to L1), R represents an 8- to 40-carbon, branched-chain or straight-chain, nonsubstituted alkyl group, and n represents 0 when L1 is a group other than â€”Oâ€”, n represents 1 when L1 is â€”Oâ€” and L2 is â€”CH2CONHâ€”, and n represents an integer from 0 to 10 when L1 is â€”Oâ€” and L2 is â€”CH2CH2Oâ€”, provided that two or more groups of R11 to R15 are not simultaneously branched-chain or straight-chain, nonsubstituted alkyl groups.
