ABSTRACT:
The present invention relates to the new nitro bezene dye of formula: ##STR1## and the cosmetically acceptable salts of this compound, as well as the process for preparation thereof by condensation of 3-amino-1-propanol with 2-fluoro-5-bis(.beta.-hydroxyethyl)amino-1-nitrobenzene.
This blue dye shows excellent solubility in water, a water/alcohol mixture and the usual dyeing media. Furthermore, when used in combination with one or more yellow nitro benzene dyes and optionally other direct dyes, it gives, especially on hair sensitized by treatment such as bleaching or permanent waving, natural shades having good lightfastness and washing resistance.
