Described herein is a composite article comprising a substrate and a multilayer coating provided on at least one surface of the substrate. The multilayer coating comprises (i) a wear-resistant layer adjacent to the substrate, the wear-resistant layer comprising inorganic oxide nanoparticles and a polymer binder, and (ii) adjacent to the wear-resistant layer, An antireflective layer opposite the material, the antireflective layer comprising a fluorosilane polymer, the fluorosilane polymer comprising: Formula (I) (Where R 1 represents H or methyl; L 1 represents a covalent bond or a divalent aliphatic group having 1 to 10 carbon atoms, Each Y 1 independently represents a hydrocarbyl group having from 1 to 6 carbon atoms; Each Y 2 independently represents a hydrolyzable group; g is 0, 1 or 2) and at least one monomer unit A Formula (I) (Where R 2 , R 3 , and R 4 represent H, methyl, trifluoromethyl, or F, at least one of R 2 , R 3 , and R 4 is F; R f 1 is a covalent bond or-(CF 2 O) a -,-(CF 2 CF 2 O) b -,-(CF 2 CF 2 CF 2 O) c -,-(CF 2 CF 2 CF 2 CF 2 O) d -,-(CF 2 CF (CF 3 ) O) e -and a divalent group selected from the group consisting of these, wherein a, b, c, d and e are Represents an integer in the range of 0 to 130, 1 ≦ a + b + c + d + e ≦ 130, R f 2 is a perfluoroalkyl group) and includes at least one divalent monomer unit B.
