  • nitroisatins of formula I and the compounds of component B can either be stored separately or together, either in a liquid to pasty preparation (aqueous or anhydrous) or as a dry powder. If the components are stored together in a liquid preparation, this should largely reduce the reaction of the components be anhydrous. When stored separately, the reactive components are only intimately mixed with one another immediately before use. In dry storage, a defined amount of warm (30 to 80 ° C) water is usually added before use and a homogeneous mixture is produced.
  • a slurry of 5 mmol of nitroisatin with the formula I, 5 mmol of an oxidation dye precursor of component B and 5 mmol of sodium acetate and a drop of a 20% fatty alkyl ether sulfate solution in 50 ml of water at 60 ° C. were prepared.
  • the slurries were mixed together at 30 ° C. and adjusted to a pH of 6 using dilute sodium hydroxide solution or hydrochloric acid.
  • a strand of 90% gray, untreated human hair was placed in this coloring solution at 30 ° C. for 30 minutes.
  • the tress was then rinsed with lukewarm water for 30 seconds, dried with warm air and then combed out.
  • the color depth was rated on the following scale:
