Dans cette formule, Y1, Y2, Y3 et Y4 désignent indépendamment les uns des autres, un atome d'azote ou un groupe méthine, sélectionné parmi les restes C-R, dans lequel R désigne un atome d'hydrogène, un atome d'halogène, un groupe hydroxy, un groupe cyano, un groupe nitro, un groupe carboxyle, un groupe sulfonamido, un groupe alkyle (C1-C6), un groupe alcoxy (C1-C6), un groupe alkényle (C2-C6), un groupe aryle éventuellement substitué, un hétérocycle éventuellement substitué, un groupe aryle-alkyle (C1-C6), un groupe hydroxyalkyloxy (C2-C6), un groupe hydroxyalkyle (C2-C6), un groupe polyhydroxyalkyle (C2-C6), un groupe RIRIIN-(CH2)m, où RI et RII désignent indépendamment l'un de l'autre un groupe alkyle (C1-C6), un groupe alkényle (C1-C6) ou un groupe aryle-alkyle C1-C6, RI et RII pouvant former conjointement avec l'atome d'azote un composé cyclique à 5, 6 ou 7 chaînons et m désigne un nombre 0, 1, 2, 3, 4, 5, ou 6 et X désigne un atome d'oxygène, un atome de soufre ou un groupe NR', R' désignant un atome d'hydrogène un groupe alkyle (C1-C6), un groupe alkényle (C2-C6), un groupe aryle-alkyle (C1-C6), un groupe hydroxyalkyle (C2-C6), un groupe alcoxy (C1-C6)-alkyle (C2-C6) ou un groupe polyhydroxyalkyle (C2-C6), sous réserve qu'au moins un reste parmi Y1, Y2, Y3 et Y4 désigne un atome d'azote. Ces agents colorants s'utilisent en particulier pour raviver la couleur ou nuancer des fibres à base de kératine, d'ores et déjà colorées.
