Abstract:
1. A coating composition comprising a fluorine-containing silicon compound represented by the following formula (1) wherein Z is a linear or branched divalent polyorganosiloxane residue having 2 to 40 siloxane units, R is an alkyl group having 1 to 4 carbon atoms or a phenyl group, X may be the same with or different from each other and is a hydrolyzable group, Q is a C 2-12 divalent connecting group which may have an oxygen and/or nitrogen atom, a is an integer of 2 or 3, b is 1, y is an integer of 1 to 5, and Rf is a group represented by the following formula (2) wherein Rf 1 is a perfluoropolyether residue, W is an organopolysiloxane residue having 3 to 40 siloxane units wherein W may be branched and may have a silalkylene group, and Q is as defined above and may be the same with or different from each other, and q is an integer of from 0 to 3, wherein said fluorine-containing silicon compound has at least seven siloxane units per molecule, and at least one solvent selected from the group consisting of alcohols, esters, ethers, ketones, and perfluoroethers.
