摘要

An antisoiling coating for an antireflective surface, particularly the outer surface of an antireflective film stack, wherein the antisoiling coating includes a fluorinated siloxane, preferably prepared by applying a coating composition of a fluorinated silane of the following formula: Rf-R1-SiX3-xR2xwherein: Rf is a perfluorinated group optionally containing one or more heteroatoms; R1 is a divalent alkylene group, arylene group, or mixture thereof, substituted with one or more heteroatoms or functional groups, containing about 2 to about 16 carbon atoms; R2 is a lower alkyl group; X is a halide, a lower alkoxy group, or an acyloxy group; and x is 0 or 1.
