, (2008/06/13)

Novel compounds of the general formula STR1 wherein Z represents a substituted lower alkyl radical; each of R1 and R2 is hydrogen atom, a lower alkyl or a substituted lower alkyl identical with or different from Z and the functional groups NO2 and NR1 R2 can occupy all ring positions in relation to OZ, with the exception that if Z is β-hydroxyethyl, --NO2 is in the 4 position and --N(R1)(R2) is in the 2 position then either R1 or R2 is other than hydrogen. The novel compounds are for dyeing human hair in a variety of yellow shades. The compounds of formula (I) may be used as aqueous or water-alcohol solutions to form dye compositions for dyeing human hair.
