  • the agent (a) is characterized by its content of at least one organic silicon compound (a1) and an acetophenone derivative.
  • the agent (b) contains at least one sealing reagent (b1).
  • either agent (a) or agent (b) or both agents (a) and (b) contain at least one color-providing compound from the group of pigments and/or direct dyes.

  • the agent (a) used in the method described above can be prepared from the agents (a') and (a").
  • Oxidation colorants are usually used for permanent, intensive colorations with good fastness properties and good gray coverage. Such colorants usually contain oxidation dye precursors, so-called developer components and coupler components, which form the actual dyes with one another under the influence of oxidizing agents such as hydrogen peroxide. Oxidation coloring agents are characterized by very long-lasting coloring results.
  • color pigments are generally understood to mean insoluble, color-imparting substances. These are present in undissolved form in the form of small particles in the coloring formulation and are only deposited from the outside on the hair fibers and/or the surface of the skin. Therefore, they can usually be cleaned with a few washes with detergents containing surfactants remove without residue.
  • Various products of this type are available on the market under the name of hair mascara.
  • EP 2168633 B1 deals with the task of producing long-lasting hair coloring using pigments.
  • the document teaches that when using the combination of a pigment, an organic silicon compound, a film-forming polymer and a solvent, colorations can be produced on hair which are particularly resistant to abrasion and/or shampooing.

  • the color-providing compounds can be permanently fixed on the keratinic material, so that extremely wash-fast colorations with good resistance to abrasion and/or shampooing could be obtained.
  • the film formation of the organic silicon compound (a1) could be significantly improved with the aid of the at least one hydroxyacetophenone. This made it possible to obtain extremely rub-fast and wash-fast colorations with good resistance to abrasion and/or shampooing.
