摘要

An intermediate transfer member containing a layer of a siloxyfluorocarbon networked polymer. A method of preparing an intermediate transfer member including mixing a coating solution containing siloxyfluorocarbon precursor materials; applying the coating solution as a sol on a substrate; curing the coating solution on the substrate to form an intermediate transfer member containing a layer of a siloxyfluorocarbon networked polymer. The surface free energy of the intermediate transfer member may be from about 10 mN/m to about 40 mN/m. A method of printing an image to a substrate includes applying an inkjet ink to an intermediate transfer member containing a layer of a siloxyflurocarbon networked polymer; spreading the ink onto the intermediate transfer member; inducing a property change of the ink; and transferring the ink to a substrate.

1. An intermediate transfer member comprising a layer of a siloxyfluorocarbon networked polymer prepared from siloxyfluorocarbon monomers represented by the structure:wherein R1 is an aliphatic or aromatic fluorocarbon chain; L is a CaH2a linker group, where a is a number between 0 and about 10; and X1, X2, and X3 are reactive hydroxide functionalities, reactive alkoxide functionalities, unreactive aliphatic functionalities of from about 1 carbon atom to about 10 carbon atoms, or unreactive aromatic functionalities including from about 3 carbon atoms to about 10 carbon atoms, wherein the surface free energy of the intermediate transfer member is from about 10 mN/m to about 40 mN/m to provide wetting of an ink applied to the intermediate transfer member and further wherein the intermediate transfer member exhibits no permanent adhesion of ink to the layer of siloxyfluorocarbon networked polymer.
