Abstract:
The subject of the present invention is the use, for dyeing in particular human keratin materials, of a specific direct anthraquinone dye by dry thermal transfer.Its subject is furthermore a method for dyeing keratin materials, in which at least one direct anthraquinone dye contained in a dry composition is applied to or close to the keratin materials, and a source of heat is applied, causing the thermal transfer of the direct dye(s) at the surface and/or inside the keratin materials.It relates furthermore to the dry composition and a method for preparing it.
