Abstract
Disclosed herein is an anhydrous composition in the form of a film comprising at least one film-forming polymer and at least one oxidation dye. Also disclosed herein is a process for preparing such a composition, comprising applying a precursor composition comprising, in a suitable solvent, a mixture comprising at least one oxidation dye and at least one polymer to a support; and evaporating off the solvent. Further disclosed herein is a process for dyeing keratin fibers, comprising contacting the fibers with the composition disclosed herein, in the presence of an aqueous medium.
