Abstract:
1. A composition for the oxidative dyeing of keratin fibres, comprising a medium suitable for dyeing and from about 0.00 1% to about 10% by weight of the composition of a compound of the formula (I), or its salts with an inorganic or organic acid, wherein R 3 , R 5 and R 6 are substituted and are independently selected from: (a) the group of C-linked monovalent substituents consisting of: (i) substituted or unsubstituted, straight or branched, alkyl, mono- or poly-unsaturated alkyl, heteroalkyl, aliphatic, heteroaliphatic, or heteroolefinic systems, (ii) substituted or unsubstituted, mono- or poly-cyclic aliphatic, aryl, or heterocyclic systems, and (iii) substituted or unsubstituted, mono-, poly-, or per-fluoro alkyl systems; said systems of (i), (ii) and (iii) independently comprising from about 1 to about 10 carbon atoms and from about 0 to about 5 heteroatoms independently selected from O, S, N, P, and Si; (b) the group of S-linked substituents consisting of SA (c) the group of O-linked substituents consisting of OA (d) the group of N-linked substituents consisting of NA (e) the group of substituents consisting of COOA (f) the group of fluoroalkyl substituents consisting of mono-, poly-, and per-fluoro alkyl systems comprising from about 1 to about 12 carbon atoms and from about 0 to about 4 heteroatoms, wherein, A 16 , A 17 , and A 18 are monovalent and are independently selected from: (1) H, (2) substituted or unsubstituted, straight or branched, alkyl, mono- or poly-unsaturated alkyl, heteroalkyl, aliphatic, heteroaliphatic, or heteroolefinic systems, (3) substituted or unsubstituted, mono- or poly-cyclic aliphatic, aryl, or heterocyclic systems, and (4) substituted or unsubstituted, mono-, poly-, or per-fluoro alkyl systems; said systems of (2), (3) and (4) comprising independently from about 1 to about 10 carbon atoms and from about 0 to about 5 heteroatoms independently selected from O, S, N, P, and Si; and wherein X is a halogen selected from the group consisting of F, Cl, Br, and I, and wherein A 19 is monovalent and independently selected from (1) substituted or unsubstituted, straight or branched, alkyl, mono- or poly-unsaturated alkyl, heteroalkyl, aliphatic, heteroaliphatic or heteroolefinic systems, (2) substituted or unsubstituted, mono or poly-cyclic aliphatic, aryl, or heterocyclic systems, and (3) substituted or unsubstituted, mono-, poly- or per-fluoro alkyl systems; said systems of (2) and (3) comprising independently from about 2 to about 10 carbon atoms and from about 0 to about 5 heteroatoms independently selected from O, S, N, P and Si, and wherein X is a halogen selected from the group consisting of F, Cl, Br and I and A 20 is monovalent and is independently selected from: (1) substituted or unsubstituted, straight or branched, alkyl, mono- or poly-unsaturated alkyl, heteroalkyl, aliphatic, heteroaliphatic, or heteroolefinic systems, (2) substituted or unsubstituted, mono- or poly-cyclic aliphatic, aryl, or heterocyclic systems, and (3) substituted or unsubstituted, mono-, poly-, or per-fluoro alkyl systems; said systems of (1), (2) and (3) independently comprising from about 1 to about 10 carbon atoms and from about 0 to about 5 heteroatoms independently selected from O, S, N, P, and Si; and wherein X is a halogen selected from the group consisting of F, Cl, Br, and I and wherein R 2 is selected from any of the groups (a), (b), (c), (d), (e) and (f) and H.
