Claim:
A hair dyeing composition comprising: a) at least one coupler selected from the group consisting of compounds according to the following formula (1), formula (1-B), and formula (1-C): formula (1) wherein R is a moiety selected from the following formulae (2), (3) or (4): wherein R 1 , R 2 , R 3 , R 4 and R 5 are each independently selected from the group consisting of hydrogen, halo, hydroxyl, amino, C 1 -C 4 alkyl or haloalkyl, C 1 -C 4 alkoxy or haloalkoxy, and nitrile; formula (1-B) wherein R 1 is an aryl ring selected from the group consisting of phenyl and a 5- or 6-membered heteroaryl having one or more heteroatom selected from O, S, or N, wherein said aryl ring is unsubstituted or substituted with one or more substituents selected from the group consisting of hydrogen, halo, hydroxyl, amino, C 1 -C 4 alkyl or haloalkyl, C 1 -C 4 alkoxy or haloalkoxy, and nitrile; wherein R and R 2 are each independently selected from the group consisting of hydrogen, C 1 -C 5 alkyl, C 1 -C 5 monohydroxyalkyl, and C 2 -C 5 dihydroxyalkyl; and wherein Z is selected from the group consisting of C 1 -C 5 alkyl, C 1 -C 5 monohydroxyalkyl, C 2 -C 5 dihydroxyalkyl, C 1 -C 5 aminoalkyl, and C 1 -C 5 methoxyalkyl; and formula (1-C) wherein R 1 is an aryl ring selected from the group consisting of phenyl and a 5- or 6-membered heteroaryl having one or more heteroatom selected from O, S, or N, wherein said aryl ring is unsubstituted or substituted with one or more substituents selected from the group consisting of hydrogen, halo, hydroxyl, amino, C 1 -C 4 alkyl or haloalkyl, C 1 -C 4 alkoxy or haloalkoxy, and nitrile; wherein R and R 2 are each independently selected from the group consisting of hydrogen, C 1 -C 5 alkyl, C 1 -C 5 monohydroxyalkyl, and C 2 -C 5 dihydroxyalkyl; and wherein any one of A, B, X, and Y is nitrogen and the remaining of A, B, X, and Y are each carbon; b) at least one primary intermediate of the formula (5): wherein R 6 and R 7 are independently selected from the group consisting of hydrogen, C 1 -C 4 alkyl, C 2 -C 4 hydroxyalkyl, benzyl, and phenyl; and wherein R 8 is selected from the group consisting of hydrogen, C 1 -C 4 alkyl, and C 2 -C 4 hydroxyalkyl; or physiologically tolerated, water-soluble salts thereof; and c) a suitable carrier.
