  The present invention relates to a cosmetic composition comprising a dispersion of particles of a grafted ethylenic polymer in a liquid fatty phase, and a film-forming agent. The film-forming agent may be soluble or dispersible in the said liquid fatty phase. The composition may contain an aqueous phase, in which case the film-forming agent may be soluble or dispersible in the aqueous phase. A subject of the invention is also the use of a combination of such a grafted ethylenic polymer and of a film-forming agent to improve the staying power and/or the transfer resistance of the said composition on keratin materials.
