摘要:
A silver halide color photosensitive material comprises at least one layer on a support. At least one of the layers contains a coupler represented by general formula (I): wherein X represents H or split-off group; R1 and R2 independently represents an electron withdrawing group whose Hammett σp value is 0.20 or greater, provided that the sum of R1 and R2 σp values is 0.65 or greater; R3 represents a group selected from alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl and heterocyclic, each of which may have a substituent; R4 represents H, or a group selected from alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, aryl, acyl, alkoxycarbonyl, aryloxycarbonyl and carbamoyl, each of which may have a substituent, provided that R3 and R4 may be bonded to form a ring; R11, R12 and R13 independently represent an alkyl group having 1-30 carbon atoms; R represents a substituent; and n represents an integer of 0-3.
