Abstract:
1. A composition for the oxidative dyeing of keratin fibers, in particular human keratin fibers, comprising: (A) a 1-hexyl/heptyl-4,5-diaminopyrazole compound of the general formula (I), a physiologically compatible water-soluble salt thereof, or mixtures thereof, wherein a is equal to one or two; wherein R (a) C-linked substituents selected from the group consisting of: wherein said C-linked substituents comprise from 1 to 6 carbon atoms and from 0 to 5 heteroatoms selected from the group consisting of O, F, N, P and Si; (b) S-linked substituents selected from the group consisting of SA (c) O-linked substituents selected from the group consisting of OA (d) N-linked substituents selected from the group consisting of NA (e) halogens selected from the group consisting of F, Cl, Br, and I; and (f) hydrogen; wherein A 1 , A 2 , and A 3 are selected independently from each other from the group consisting of: hydrogen; substituted or unsubstituted, straight or branched or cyclic, saturated or unsaturated, aliphatic or heteroaliphatic or aromatic or heteroaromatic substituents, or A 1 and A 2 together with nitrogen atoms to which they are bound form a ring; wherein said substituents or ring comprise from 1 to 6 carbon atoms and from 0 to 5 heteroatoms selected from the group consisting of O, S, N, P, and Si; wherein R wherein R (a) C-linked substituents selected from the group consisting of: wherein said C-linked substituents comprise from 1 to 10 carbon atoms and from 0 to 5 heteroatoms selected from the group consisting of O, F, N, P and Si; (b) S-linked substituents selected from the group consisting of SA (c) O-linked substituents selected from the group consisting of OA (d) N-linked substituents selected from the group consisting of NA (e) halogens selected from the group consisting of F, Cl, Br, and I; and (f) hydrogen; wherein A 1 , A 2 , and A 3 are selected independently of each other from the group consisting of: hydrogen; substituted or unsubstituted, straight or branched or cyclic, saturated or unsaturated, aliphatic or heteroaliphatic or aromatic or heteroaromatic substituents, or A 1 and A 2 together with nitrogen atoms to which they are bound form a ring; wherein said substituents or ring comprise from 1 to 10 carbon atoms and from 0 to 5 heteroatoms selected from the group consisting of O, S, N, P, and Si; wherein R (g) C-linked substituents selected from the group consisting of: wherein said C-linked substituents comprise from 1 to 6 carbon atoms and from 0 to 5 heteroatoms selected from the group consisting of O, F, N, P and Si; and (h) hydrogen; and
