    摘要： Oxidative dyeing of hair to a natural blonde or yellow coloration with exceptional wearing properties can be obtained y use of a system for oxidative hair coloring in which the hair coloring system utilizes a compound of the formula (I) wherein R1 and R2 are independently H; C1-4 alkyl, optionally substituted with one or more hydroxy- or amino groups; R1 and R2 may form a 5- or 6-membered heterocyclic ring, optionally containing one additional N- or O-heteroatom in the ring as a primary intermediate and a compound of the formula (II) wherein R1 and R2 are independently H; C1-4 alkyl or hydroxy-alkyl as a coupler and optionally a yellow direct dye or a known oxidative yellow dye.

    摘要： Primary intermediates for hair coloring compositions for oxidative dyeing of hair are compounds of the formula (1): wherein R1 and R2 are aech independently selected from hydrogen atoms, a C1 to C5 alkyl or hydroxyalkyl group, or R1 and R2 together with the nitrogen atom to which they are attached form a 5 or 6 member cyclic ring optionally containing one or more additional atoms selected from O, N or S atoms, and n is equal to 1 or 2, with the proviso that when n is equal to 2 only one of R1 and R2 may be hydrogen.
