Abstract
A fluorine-containing urethane compound of the general formula:[Rf-A-(X(OH))—(Y)—OC(═O)NH—]I[—NHC(═O)O—Y][—NHC(═O)O—((ClCH—)XO)—R]  (1)wherein I is a group remaining after an isocyanate group is removed from a polyisocyanate compound, Rf is a perfluoroalkyl group having 2 to 21 carbon atoms, Ais a direct bond or a divalent organic group having 1 to 21 carbon atoms, Xand Xare trivalent linear or branched aliphatic group having 2 to 5 carbon atoms, Yis a divalent organic group having 0 to 5 carbon atoms and 0 to 2 nitrogen atoms (provided that at least one carbon atom or nitrogen atom is present) and at least one hydrogen atom, Yis a monovalent organic group optionally having a hydroxyl group, and Ris a hydrogen atom or an alkyl group having 1 to 10 carbon atoms, can impart high water- and oil-repellency.
