L'INVENTION CONCERNE UNE COMPOSITION DE TEINTURE DES FIBRES KERATINIQUES, ET EN PARTICULIER DES CHEVEUX HUMAINS, COMPRENANT, DANS UN VEHICULE AQUEUX, ALCOOLIQUE OU HYDROALCOOLIQUE, LA 5-NITROVANILLINE DE FORMULE:(CF DESSIN DANS BOPI)CE COLORANT NITRE JAUNE PERMET D'OBTENIR DES TEINTURES STABLES AYANT UNE BONNE RESISTANCE A LA LUMIERE ET AU SHAMPOOING LORSQU'IL EST UTILISE SEUL OU EN COMBINAISON AVEC DES COLORANTS NITRES BENZENIQUES BLEUS OU VIOLETS, ET EVENTUELLEMENT AVEC D'AUTRES COLORANTS DIRECTS. The invention relates to a composition for dyeing keratinic fibres, especially human hair, which contains 5-nitrovanillin of formula: (I) in an aqueous, alcoholic or hydroalcoholic carrier.
