Abstract:
A silver halide color photosensitive material comprising at least one blue-sensitive emulsion layer, at least one green-sensitive emulsion layer, and at least one red-sensitive emulsion layer on a support, wherein the material contains a magenta coupler represented by formula (MC-1) below: wherein R1 represents a tertiary alkyl group; each of s, m, and n independently represents 0 or 1; each of R2, R3, R4, R5, R6, and R7 represents a hydrogen atom, halogen atom, alkyl group, or aryl group; L represents a divalent group selected from the group consisting of â€”NR8SO2â€”, â€”SO2NR8â€”, â€”SO2NR8COâ€”, â€”NR8COOâ€”, â€”NR8CONR9â€”, and â€”COOâ€”, wherein the right side of each formula bonds to the phenyl group in formula (MC-1); each of R8 and R9 represents a hydrogen atom, alkyl group, or aryl group; J represents a divalent group selected from the group consisting of â€”COâ€”, â€”COOâ€”, â€”Oâ€”, â€”Sâ€”, â€”CONR10â€”, â€”NR10COâ€”, â€”NR10COOâ€”, â€”NR10NR11â€”, â€”SO2â€”, â€”SO2NR10â€”, and â€”CONR10SO2â€”, wherein the left side of each formula bonds to the phenyl group in formula (MC-1); each of R10 and R11 represents a hydrogen atom, alkyl group, or aryl group; B represents an alkyl group having the total number of carbon atoms of 1 to 70 or an aryl group having the total number of carbon atoms of 6 to 70; p represents an integer from 1 to 5, a plurality of â€”Jâ€”B's being able to be the same or different when p is 2 or more; G represents a group selected from the group consisting of an alkyl group, aryl group, halogen atom, and alkoxy group; and q represents an integer from 0 to 4, a plurality of G's being able to be the same or different when q is 2 or more, provided that the following magenta coupler is excluded:
