<p>Compsn. for oxidn. dyeing of keratinic fibres, esp. human hair, contains at least one diaminopyrazole base of formula (I) or its acid-addn. salt; and at least one heterocyclic coupler (A) selected from indoles of formula (II), benzimidazoles of formula (III), benzomorpholines of formula (IV), pyridines of formula (V), indolines of formula (VI), quinolines of formula (VII), sesamols of formula (VIII) and their acid-addn. salts, provided that (II) is not 5,6-dihydroxyindole when (I) is 4,5-diamino-1-methylpyrazole. R1 = H, 1-6C alkyl, 2-4C hydroxyalkyl, benzyl (opt. substd. by halo, 1-4C alkyl or alkoxy) or phenyl; or R1+ 'the N at position 5' = hexahydropyrimidine or tetrahydroimidazole (opt. substd. by 1-4C alkyl); R2, R3 = H, 1-4C alkyl, 2-4C hydroxyalkyl, benzyl or phenyl; provided that R2 is H when R1 is substd. benzyl or forms a ring; R4 = H, 1-6C alkyl or 2-4C hydroxyalkyl. R5, R6 = H or 1-4C alkyl; R7 = H, 1-4C alkyl or OH; X = OH, NH2, 1-4C alkylamino or 1-4C hydroxyalkylamino, provided that (a) R7 is OH when it is in the 6 position, X = 5-OH and R5 = R6 = H; and (b) R5-R7 are not all H when X = 4-OH or X is in the 5-position. R9 = H or 1-4C alkyl; R10 = H, 1-4C alkyl or phenyl; R11 = OH, NH2 or OMe; R12 = H, OH, OMe or 1-4C alkyl; provided that (a) when R11 = NH2, it is in the 4 position; (b) when R11 is in the 4 position, then R12 is in the 7 position; and (c) when R11 is in the 4-position, then R12 is in the 6-position. R13, R14 = H or 1-4C alkyl; Z = OH or NH2. R15 = H, OH, NH2 or OCH2CH2COCH2CH2OH; R16. R18 = H, OH, NH2 or 1-4C alkyl; R17 = H or 1-4C alkyl; R19 = H, OH or NH2, provided that cpds. (V) do not contain more than two NH2 gps. or more than two OH gps. or more than one NH2 gp. and one OH gp., and that these NH2 and/or OH gps. must be meta to each other. R20 = H or OH; R21 = OH or NH2. R22 = OH or 1-4C alkoxy; R23 = H or NH2. R24 = NH2 and R25 = 1-4C alkoxy; or R24 = OH and R25 = halogen.</p> |
