Abstract

A fluorine-containing urethane compounds represented by the formula ##STR1## wherein R_f represents a perfluoroalkyl group having 4 to 20 carbon atoms; X represents --CH₂ CH(A)--, --C_k H_2k -- or --SO₂ N(R³)C_t H_2t -- (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 ##STR2## (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.
