Primary intermediates for hair coloring compositions for oxidative dyeing of hair are compounds of the formula (1):wherein Rand Rare each independently selected from hydrogen atoms, a Cto Calkyl or hydroxyalkyl group, or Rand Rtogether 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 Rand Rmay be hydrogen.

Primary intermediates for oxidative coloration of hair

Primary intermediates for hair coloring compositions for oxidative dyeing of hair are compounds of the formula (1):where Rand Rare each individually selected from a hydrogen atom, a Cto Calkyl group, a Cto Cmono or dihydroxyalkyl group; phenyl or benzyl optionally substituted with an alkoxy group, or Rand Rtogether with the nitrogen atom to which they are attached form a piperazine, piperidine, imidazole, or morpholine ring.

Primary intermediates for hair coloring compositions for oxidative dyeing of hair are compounds of the formula (1):wherein R is selected from Cto Calkyl or hydroxyalkyl, a Cto Ccyclic ring containing hetero atoms selected from O, S and N atoms, and &#x2014;CH&#x2014;Ar where Ar is an aromatic ring wherein the aromatic ring may be substituted with one or two hydroxy Cto Calkoxy, or amino groups.

Couplers for hair coloring compositions for oxidative dyeing of hair are compounds of the formula (1):where Rand Rare each individually selected from a hydrogen atom, a Cto Calkyl group, a Cto Cmono or dihydroxyalkyl group; phenyl or benzyl optionally substituted with an alkoxy group, or Rand Rtogether with the nitrogen atom to which they are attached form a piperazine, piperidine, imidazole, or morpholine ring.

Couplers for use in oxidative hair dyeing

Novel compositions for use in oxidative hair coloring compositions are provided. The compositions comprise one or more oxidative hair coloring N-aryl-m-phenyldiamine derivatives as couplers and one or more diaminopyrazole primary intermediates in combination.

Hair coloring compositions for use in oxidative hair dyeing

Couplers for hair coloring compositions for oxidative dyeing of hair are compounds of formula (1):wherein X is selected from halogen; Ris selected from the group consisting of Cto Calkyl and hydroxyethyl; and R, Rand Rare each independently selected from Cto Calkyl or Cto Cmono or dialkyl groups, or two of R, Rand Rtogether with the the nitrogen atom to which they are attached form a Cto Ccycloaliphatic or a Cto Caromatic group, the cycloaliphatic or aromatic group optionally containing in their rings one or more hetero atoms selected from O, S and N atoms.

Coupler for use in oxidative hair dyeing

Couplers for hair coloring compositions for oxidative dyeing of hair are compounds of the formula (1):wherein X is selected from halogen and RSOwhere the halogen is preferably Cl, Br or I; R, Rand Rare each individually selected from Cto Calkyl and Cto Cmono or dihydroxyalkyl, or two of R, Rand Rtogether with the nitrogen atom to which they are attached form a Cto Csaturated or unsaturated ring optionally containing in the ring one or more additional hetero atoms selected from O, S and N atoms; Rand Rare each individually selected from Cto Calkyl, Cto Chydroxyalkyl, Cto Calkoxy, Cto Caminoalkyl or Rand Rtogether form a Cto Calkylene group; and Ris selected from Cto Calkyl and Cto Cmono or dihydroxyalkyl.
