Substantially dry cosmetic article for dyeing of keratinous materials, preferably human hair, comprises porous flexible substrate and direct dyes/precursors of direct dyes in form of powder to dye keratinous materials by thermal transfer

摘要

Substantially dry cosmetic article (A) for the dyeing of keratinous materials, comprises a porous flexible substrate and direct dyes or precursors of direct dyes in the form of powder to dye the keratinous materials by thermal transfer. The substrate and the direct dyes or precursors of direct dyes are fixed on and/or in the substrate in a non-covalent manner. An independent claim is included for a method for dyeing the keratinous materials comprising positioning the article on or near the keratinous materials and applying a source of heat involving the heat transfer of the dyes on or in the keratinous materials.
