Fluorinated phosphonic acid compounds, useful as treatments for substrate surfaces, have the formula (I) : wherein: R?1? is a straight chain alkylene group having from 3 to 21 carbon atoms, an oxa-substituted straight chain alkylene group having from 2 to 20 carbon atoms, or a thia-substituted straight chain alkylene group having from 2 to 20 carbon atoms; R?2? is a perfluoroalkyl group having from 4 to 10 carbon atoms; R?3? is hydrogen, an alkali metal cation, or an alkyl group having from 1 to 6 carbon atoms; and M is hydrogen or an alkali metal cation, with the proviso that if R?1? is an unsubstituted straight chain alkylene group, then the sum of carbon atoms in R?1? and R?2? combined is at least 10.
