Anhydrous composition in the form of a film comprising a film-forming polymer and oxidizing agent, preparation and process for coloring keratinous fibers employing the anhydrous composition

摘要

The present disclosure relates to an anhydrous composition in the form of a film comprising at least one film-forming polymer and at least one oxidizing agent. The present disclosure also relates to a process for the preparation of such a composition in which a precursor composition comprising, in an appropriate solvent, a mixture comprising at least one oxidizing agent and at least one film-forming polymer is applied to a support and then the solvent is evaporated. The present disclosure also relates to a process for dyeing keratinous fibers which comprises bringing the fibers and the composition into contact in the presence of an aqueous medium.
