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.
