ABSTRACT:
Couplers for hair coloring compositions for oxidative dyeing of hair are compounds of the formula (1):wherein X is selected from halogen and R5SO4where the halogen is preferably Cl, Br or I; R, R1and R2are each individually selected from C1to C22alkyl and C1to C22mono or dihydroxyalkyl, or two of R, R1and R2together with the nitrogen atom to which they are attached form a C3to C6saturated or unsaturated ring optionally containing in the ring one or more additional hetero atoms selected from O, S and N atoms; R3and R4are each individually selected from C1to C6alkyl, C1to C6hydroxyalkyl, C1to C6alkoxy, C1to C6aminoalkyl or R3and R4together form a C1to C5alkylene group; and R5is selected from C1to C22alkyl and C1to C22mono or dihydroxyalkyl.
