Title (EN) OXIDATIVE COLORING REAGENTS
(FR) REACTIFS COLORANTS OXYDATIFS
Abstract:
(EN) Compounds represented by general formula (I) wherein R1 and R2 are each independently C1-C6 alkyl; R3 and R4 are each independently hydrogen or C1-C6 alkyl; and R5 and R6 are each independently hydrogen, monosulfonated C1-C6 alkyl optionally having one or more hydroxyl groups, or the like, exclusive of cases where both R5 and R6 are hydrogen simultaneously, or salts thereof; and oxidative coloring reagents containing the compounds or the salts.
(FR) L'invention concerne des composés représentés par la formule générale (I), dans laquelle R1 et R2 sont chacun indépendamment alkyle C1-C6, R3 et R4 sont chacun indépendamment hydrogène ou alkyle C1-C6, et R5 et R6 sont chacun indépendamment hydrogène, alkyle C1-C6 monosulfoné possédant éventuellement un ou plusieurs groupes hydroxyle, ou similaire, à l'exclusion des cas où R5 et R6 sont tous deux simultanément hydrogène, ou bien des sels composés. L'invention concerne également des réactifs colorants oxydatifs contenant ces composés ou leurs sels.
