Primary intermediates for hair coloring compositions for oxidative of hair are compounds of the formula (1): where R1 and R2 are each individually selected from a hydrogen atom, a C1 to C3 alkyl group, a C1 to C5 mono or dihydroxyalkyl group; phenyl or benzyl optionally substituted with an alkoxy group, or R1 and R2 together with the nitrogen atom to which tey are attached form a piperazine, piperidine, imidazole, or morpholine ring.
L'invention concerne des intermédiaires primaires pour des compositions de coloration capillaire destinées à effectuer une teinture oxydative des cheveux. Ces intermédiaires sont des composés représentés par la formule (1): dans laquelle R¿1? et R¿2? sont chacun individuellement choisis dans un groupe constitué d'un atome d'hydrogène, d'un groupe alkyle C¿1?-C¿3?, d'un groupe mono ou dihydroxyalkyle C¿1?-C¿5?; de phényle ou de benzyle éventuellement substitués par un groupe alcoxy ou R¿1? et R¿2?, conjointement avec l'atome d'azote auquel ils sont fixés, forment un noyau piperazine, piperidine, imidazole ou morpholine.
