Couplers for hair coloring compositions for oxidative dyeing of hair are compounds of formula (1): wherein X is selected from halogen; R3 is selected from the group consisting of C1 and C2 alkyl and hydroxyethyl; and R and R1 and R2 are each independently selected from C1 to C22 alkyl or C1 to C22 mono or dialkyl groups, or two of R, R1 and R2 together with the nitrogen atom which they are attached form a C3 to C6 cycloaliphatic or a C3 to C14 aromatic group, the cycloaliphatic or aromatic group optionally containing in their rings one or more hetero atoms selected from O, S and N atoms.

Agents de couplage de compositions de coloration pour la teinture oxydante des cheveux consistant en des composés représentés par la formule (1), dans laquelle X est sélectionné dans halogène; R?3¿ est sélectionné dans le groupe constitué par alkyle C¿1?-C¿2? et hydroxyéthyle; R, R?1¿ et R?2¿ sont sélectionnés indépendamment chacun dans alkyle C¿1?-C¿22? ou dans des groupes mono ou dialkyle C¿1?-C¿22? ou deux de R, R?1¿ et R?2¿ avec l'atome d'hydrogène auquel ils sont fixés, constituent un groupe cyclo-aliphatique C¿3?-C¿6? ou un groupe aromatique C¿3?-C¿14?, ces groupes cyclo-aliphatique ou aromatique contenant éventuellement dans leurs chaînes un ou plusieurs hétéro atomes sélectionnés dans des atomes d'O, S et N.
