, (2008/06/13)
2-nitroaniline derivatives of the general formula I: STR1 in which R1 and R2 represent, independent of one another, hydrogen, an alkyl of 1 to 4 carbon atoms, a monohydroxyalkyl of 2 to 4 carbon atoms or a dihydroxyalkyl of 3 or 4 carbon atoms, provided that R1 and R2 do not simultaneously represent alkyl groups of 1 to 4 carbon atoms, and X denotes an alkyl, monohydroxyalkyl, perfluoroalkyl or halogen, for use as an agent in a hair dyeing composition. Also disclosed are new 2-nitroaniline derivatives of the general formula II: STR2 in which Ra and Rb denote, independent of one another, ethyl, a monohydroxylalkyl of 2 to 4 carbon atoms or a dihydroxyalkyl of 3 or 4 carbon atoms, when Z is methyl, Cl or Br; or when Z is CH2 OH or a perfluoroalkyl, Ra denotes hydrogen, a monohydroxyalkyl of 2 to 4 carbon atoms or a dihydroxyalkyl of 3 or 4 carbon atoms, and Rb represents 2-hydroxyethyl or 2,3-dihydroxypropyl.
