摘要（英）：

Disclosed are compounds of formula (1a), wherein R1 is N<+>R8R9; R8 and/or R9 independently from each other are hydrogen; C1-C12 alkyl; or phenyl-C1-C4-alkyl; or R8 and/or R9 are a bivalent C3-C6alkylene radical which is linked to the carbon atoms C1 or C2 respectively and, together with the linking nitrogen atom form a 6 to 16-membered carbocyclic ring; R2 is NR10R11; or OR10; R10 and R11, independently from each other are hydrogen; C1-C12 alkyl; or phenyl-C1-C4alkyl; or R10 and/or R11 are a bivalent C3-C6alkylene radical which is linked to the carbon atoms C3 or C4 respectively and, together with the linking nitrogen or oxygen atom form a 6 to 16- membered carbocyclic ring; or R10 and R11 together with the linking nitrogen atom form a 4 to 8 membered carbocyclic ring; R3, R4, R5, R6 and R7 independently from each other are hydrogen; C1-C12alkyl; halogen; NR12R13; or a radical of formula (1a1); R12 and R13 independently from each other are hydrogen; C1-C12 alkyl; phenyl-C1-C4 alkyl; or a radical of formula (1a2); V is -O-; Or -NR15; R14, R15 R-16 and R17 independently from each other are hydrogen; or C1-C5alkyl; and Hal is a halogen atom; and wherein at least one of R3, R4, R5, R6 and R7 is hydrogen. The compounds are useful for dyeing of keratin-containing fibres with or without reducing agents.
