The invention relates to a cosmetic process for the care or makeup of keratin materials, comprising the topical application to keratin materials of a cosmetic composition comprising a phosphonic polymer resulting from the polymerization of: (a) 45 to 95% by weight, ethylenic monomer having at least one C8 alkyl group, linear or branched; (b) 5 to 25% by weight of vinylphosphonic acid monomer; (c) 0 to 50% by weight of additional monomer chosen from linear or branched C1-C6 alkyl (meth) acrylates, (C6-C12) cycloalkyl (meth) acrylates, and mono-terminated polydimethylsiloxanes ( meth) acryloyloxy, optionally combined with an additional compound chosen from polyamine compounds having several primary amine and / or secondary amine groups, aminosilanes, divalent or trivalent metal ion salts, clays, metal oxides. The process makes it possible to obtain a film-forming deposit having good resistance to water, oil and sebum. The film is also non-sticky and non-transferable. The invention also relates to the polymers containing the 3 monomers (a), (b) and (c). |
