Fluorine containing urethane compounds

摘要

A fluorine-containing urethane compounds represented by the formula <IMAGE> (I) wherein Rf represents a perfluoroalkyl group having 4 to 20 carbon atoms; X represents -CH2CH(A)-, -CkH2k- or -SO2N(R3)CtH2t- (in which A represents a methyl group or ethyl group; k and t are an integer of 1 to 4; and R3 is hydrogen atom or a lower alkyl group); R1 represents a n-valent organic group; R2 represents an alkyl group having 1 to 5 carbon atoms; n is an integer of 2 to 10; and m is an integer in the range of n>/=m>/=1, subject to the limitation that when n is 2, m is 2 and R1 is <IMAGE> (in which Y is a divalent organic group) and a water and oil-repelling agent and a non-sticking agent containing the compound as the active ingredient.
