2-nitroaniline derivatives

Abstract

Abstract 2-nitroaniline derivatives of the general formula I: ##STR1## in which R 1 and R 2 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 R 1 and R 2 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 R a and R b 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 CH 2 OH or a perfluoroalkyl, R a denotes hydrogen, a monohydroxyalkyl of 2 to 4 carbon atoms or a dihydroxyalkyl of 3 or 4 carbon atoms, and R b represents 2-hydroxyethyl or 2,3-dihydroxypropyl.
