Abstract:
A composition for coloring keratin fibers based on a developer-coupler combination, said composition comprising at least one developer compound and 3-(2,4-diaminophenoxy)-1-propanol, said 3-(2,4-diaminophenoxy)-1-propanol acting as a coupler;wherein said at least one developer compound is selected from the group consisting of p-phenylenediamine derivatives of formula I: â€ƒwherein m=0 or 1 and R1 is a straight-chain C3- to C6-alkyl group, branched C3- to C6-alkyl group, a straight-chain C1- to C6-alkyl group, branched monohydroxy-(C1-C6)-alkyl group, or a polyhydroxy-(C2-C6)-alkyl group, a straight-chain mono-(C2-C6)-alkoxy-(C2-C6)-alkyl group, branched mono-(C2-C6)-alkoxy-(C2-C6)-alkyl group, poly-(C2-C6)-alkoxy-(C2-C6)-alkyl group, a carbocyclic or heterocyclic, substituted or unsubstituted aromatic compound: 4,5-diamino-1H-pyrazole compounds of formula II: â€ƒwherein R2, R4 and R5, independently of each other, denote a hydrogen atom, a straight-chain C1- to C6-alkyl group branched C1- to C6-alkyl group, a straight-chain monohydroxy-(C1-C6)-alkyl group branched monohydroxy-(C1-C6)-alkyl group, a polyhydroxy-(C2-C6)-alkyl group, an unsubstituted benzyl group, a substituted benzyl group substituted on a benzene ring thereof, and R3 denotes a straight-chain C1- to C6-alkyl group, branched C1- to C6-alkyl group, a straight-chain monohydroxy-(C1-C6)-alkyl group branched monohydroxy-(C1-C6)-alkyl group, a polyhydroxy-(C2-C6)-alkyl group, a straight-chain mono-(C2-C6)-alkoxy-(C2-C6)-alkyl group branched mono-(C2-C6)-alkoxy-(C2-C6)-alkyl group, poly-(C2-C6)-alkoxy-(C2-C6)-alkyl group, a carbocyclic, heterocyclic, substituted aromatic compound, unsubstituted aromatic compound, or wherein R2 denotes a methyl group, an isopropyl group, a 2-hydroxyethyl group, a benzyl group, or a 4-methylbenzyl group, when R3, R4 and R5 are each said hydrogen atom; and p-aminophenol derivatives of formula III: â€ƒwherein R6 is a straight-chain C1- to C6-alkyl group branched C1- to C6-alkyl group, a straight-chain monohydroxy-(C1-C6)-alkyl group branched monohydroxy-(C1-C6)-alkyl group, a polyhydroxy-(C2-C6)-alkyl group, a straight-chain mono-(C2-C6)-alkoxy-(C2-C6)-alkyl group branched mono-(C2-C6)-alkoxy-(C2-C6)-alkyl group, poly-(C2-C6)-alkoxy-(C2-C6)-alkyl group, a carbocyclic, heterocyclic, substituted or unsubstituted aromatic compound.
