摘要： The present invention pertains to an aqueous composition comprising: (A) at least one functional fluorinated polymer [polymer (F)] selected from: - a fluorinated ionisable polyurethane polymer [polymer (PUR)] comprising at least one fluorinated block comprising a (per)fluoropolyoxyalkylene chain [chain (R OF )] and at least one functional block comprising a hydrocarbon chain [chain (R H )] optionally comprising one or more aromatic or cycloaliphatic groups, said chain (R H ) comprising at least one ionisable group, said blocks being linked by urethane moieties having formula (I) here below: wherein E is a divalent hydrocarbon group, linear or branched, optionally comprising one or more cycloaliphatic or aromatic groups, and - a fluorinated polymer [polymer (P)] comprising one or more perfluoroalkyl chains [chain (R F )] linked by one or more ester moieties having formula (II) and/or urethane moieties having formula (III) and/or urea moieties having formula (IV) here below: (B) at least one functional hydrogenated polymer [polymer (H)] different from said polymer (F), said polymer (H) comprising at least one functional group; (C) at least one cross-linking agent; wherein the weight ratio of the polymer (F) to the polymer (H) is higher than 0.75.
