Abstract Provided is a coating agent comprising a fluoropolyether group-containing polymer composition that contains, at a specific ratio: a polymer and/or a partial (hydrolyzed) condensate (I) thereof, the polymer having a fluorooxyalkyl group at one end thereof, and at least two reactive functional groups at the other end thereof; and a polymer and/or a partial (hydrolyzed) condensate (II) thereof, the polymer having a fluorooxyalkylene group in a molecule, and a reactive functional group bonded to both ends of the fluorooxyalkylene group via a linking group that does not have a polar group. By using the coating agent, a cured film can be formed that has excellent water and oil repellency, and abrasion durability, and that maintains high abrasion durability even after surface cleaning. Selon l'invention, un agent de revêtement qui contient une composition polymère à teneur en groupe fluoropolyéther permet de former un film durci doté d'excellentes propriétés hydrofuges et oléofuges et d'une excellente durabilité à l'abrasion, et conservant une durabilité à l'abrasion élevée y compris après nettoyage de sa surface. La composition polymère à teneur en groupe fluoropolyéther comprend en proportions spécifiques : (I) un polymère possédant un groupe fluorooxyalkyle à une extrémité, et au moins deux groupes fonctionnels réactifs à l'autre extrémité, et/ou un produit de (hydrolyse) condensation partielle de ce polymère ; et (II) un polymère qui possède un groupe fluorooxyalkylène à l'intérieur de chaque molécule, et qui possède un groupe fonctionnel réactif lié aux deux extrémités dudit groupe fluorooxyalkylène par l'intermédiaire d'un groupe de liaison exempt de groupes polaires, et/ou un produit de (hydrolyse) condensation partielle de ce polymère. 一方の末端にフルオロオキシアルキル基を有し、他方の末端に反応性官能基を2個以上有するポリマー及び/又はその部分(加水分解)縮合物(I)と、分子内にフルオロオキシアルキレン基を有し、該フルオロオキシアルキレン基の両末端に極性基を有さない連結基を介して結合した反応性官能基を有するポリマー及び/又はその部分(加水分解)縮合物(II)とを特定割合で含有してなるフルオロポリエーテル基含有ポリマー組成物を含むコーティング剤が、撥水撥油性、摩耗耐久性に優れ、表面洗浄後も高い摩耗耐久性を維持する硬化被膜を形成し得る。
