摘要:
The invention relates to a dye composition for keratinic fibers comprising an oxidation colorant precursor of the type ortho and/or para and a sulfured metaphenylenediamine having formula (I) ##STR1## wherein Z is alkyl, aralkyl, monohydroxyalkyl or polyhydroxyalkyl, aryl or aminoalkyl, as well as the acid salts thereof, with the condition that R.sub.1 and R.sub.2 do not represent simultaneously hydrogen when Z is alkyl or hydroxyalkyl, as well as the acid salts corresponding to the compounds of formula (I).
摘要:
Novel nitrobenzene compounds of the nitroparaphenylenediamine type substituted by sulphur in the 5-position are disclosed. These compounds are intended especially for the dyeing of keratin fibres and in particular human hair. A process for their preparation, dyeing compositions in which these compounds are present and a dyeing process in which these compositions are used are also disclosed.
