L'invention concerne une 2-nitro métaphénylènediamine de formule :
dans laquelle Z désigne le radical -O-, -S- ou -NH- et R₁, R₂ et R₃, identiques ou différents désignent un atome d'hydrogène, un radical alkyle, hydroxyalkyle, polyhydroxyalkyle, alcoxyalkyle, hydroxyalcoxyalkyle ou aminoalkyle dont le radical amino peut être mono ou disubstitué par un radical alkyle ou hydroxyalkyle, les radicaux alkyle et alcoxy comportant 1 à 6 atomes de carbone, ou les sels cosmétiquement acceptables de ce composé ainsi que son procédé de préparation.
Ce composé est utilisé en teinture des cheveux.
