Definitions

  • This invention relates to bicyclic fused 5-5-membered aza heteroaromatic keratin dyeing compounds having a ring junction nitrogen and an N-hydroxy or N-amino group and derivatives thereof and compositions for the oxidative dyeing of keratin fibers (preferably hair) comprising such compounds, and use thereof.
  • the most extensively used method currently employed to color hair is by an oxidative process that utilizes one or more oxidative hair coloring agents in combination with one or more oxidizing agents.
  • a peroxy oxidizing agent is used in combination with one or more developers or couplers, generally small molecules capable of diffusing into hair.
  • a peroxide material such as hydrogen peroxide, activates the developers so that they react with the couplers to form larger sized compounds in the hair shaft to give a variety of shades and colors.
  • This invention relates to bicyclic fused 5-5-membered aza heteroaromatic keratin dyeing compounds having a ring junction nitrogen and an N-hydroxy or N-amino group and derivatives thereof according to the formulas defined herein.
  • This invention also relates to a composition for the oxidative dyeing of keratin fibers, comprising a medium suitable for dyeing and bicyclic fused 5-5-membered aza heteroaromatic keratin dyeing compounds having a ring junction nitrogen and an N-hydroxy or N-amino group and derivatives thereof.
  • This invention further relates to a method for oxidative dyeing of keratin fibers, comprising applying such compositions in the presence of an oxidizing agent, for a period sufficient to develop the desired coloration.
  • the keratin dyeing compounds of the present invention can act as a developer and/or a coupler. It is to be understood that within the scope of this invention, numerous potentially and actually tautomeric compounds are involved. Thus, for example, 2-mercaptopyridine (I) exists under known conditions in the pyridine-2-thione tautomer form (II).
