| titleOfInvention | Metaphenylendiamines, process for their preparation, intermediate compounds and use of these metaphenylendiamines as couplers in oxydative colouring of keratinic fibres especially of human hair |
| abstract | Compounds of formula: n<IMAGE>n in which R1 and R2 independently of each other denote a hydrogen atom, a C1-C4 alkyl radical or a C2-C3 mono- or polyhydroxyalkyl radical,n Z and Z' independently of each other denote a C1-C4 alkyl or C2-C4 hydroxyalkyl radical, provided that when R1 and R2 simultaneously denote a hydrogen atom, Z and Z' do not simultaneously denote the methyl radical, and their addition salts with an acid, process for their preparation and their use as couplers in an aqueous carrier, in combination with at least one precursor of a para-type oxidation dye for dyeing human hair. n<??>The invention also relates to the intermediate compounds of formula n<IMAGE>n in which R' denotes a hydrogen atom, a C1-C4 alkyl radical, a C2 or C3 mono- or polyhydroxyalkyl, acetyl or chloroethoxycarbonyl radical and Z and Z' independently of each other denote a C1-C4 alkyl radical. |
