PROBLEM TO BE SOLVED: To provide a reactive fluorine-containing oligomer for modifying the surface of a molding consisting of a resin, glass, metal, etc. capable of conferring excellent antifouling properties such as water/oil repellency, fingerprint wipe-off capacity, etc. and of lastingly preserving the excellent antifouling properties.SOLUTION: The provided reactive fluorine-containing oligomer is obtained by reacting an isocyanate group-containing (meth)acrylate with the hydroxyl group of a hydroxyl group-containing copolymer including, as a monomer component, a (meth)acrylate expressed by the following general formula D (in the formula D, Rfis a perfluoroalkylene group having 1-5 carbon atoms; Ris a single bond or an alkylene group having 1-5 carbon atoms; Ris a monovalent organic group having at least two (meth)acryloyl groups; m+n is an integer of 5 to 50). |
