A method of modifying a surface of a substrate comprises: inkjet printing a material, the material comprising a non-vaporizable component onto a surface of a substrate, wherein the non-vaporizable component comprises at least one compound having the formula n R f —Z—X n wherein R f is a perfluoroalkyl group having from 1 to 22 carbon atoms; Z is a divalent connecting group or a covalent bond; X is selected from the group consisting of —PO 3 H, —CO 2 H, n n n and salts thereof; and wherein the compound comprises greater than 10 percent by weight of the non-vaporizable component. Various articles may be produced according to the method. |
