Abstract:

Described herein is composite article comprising a substrate; and on at least one face of the substrate a multilayered coating disposed thereon. The multilayered coating comprises (i) an abrasion-resistant layer adjacent to the substrate, wherein the abrasion-resistant layer comprises inorganic oxide nanoparticles and a polymer binder; and (ii) an antireflection layer adjacent to the abrasion-resistant layer opposite the substrate, wherein the antireflection layer comprises a fluorosilane polymer, wherein the fluorosilane polymer comprises: at least one monomeric unit A represented by the formula (I) wherein Rrepresents H or methyl, Lrepresents a covalent bond or a divalent aliphatic group having from 1 to 10 carbon atoms, each Yindependently represents a hydrocarbyl group having from 1 to 6 carbon atoms, each Yindependently represents a hydrolyzable group, g is 0, 1, or 2; and at least one divalent monomeric unit B represented by the formula (I) wherein R, R, and Rrepresent H, methyl, trifluoromethyl, or F, wherein at least one of R, R, and Ris F, Rrepresents a covalent bond or a divalent group selected from the group consisting of —(CFO)—, —(CFCFO)—, —(CFCFCFO)—, —(CFCFCFCFO)—, —(CFCF(CF)O)—, and combinations thereof, wherein a, b, c, d, and e represent integers in the range of from 0 to 130, and wherein 1≦a+b+c+d+e≦130, and Ris a perfluoroalkyl group.

Abstract:

An anti-fog coating composition is described comprising an aqueous polymeric dispersion; a crosslinker, and a surfactant. The dried and cured coating composition does not exhibit fogging within 8 seconds after being soaked in 25 C. water for 1 hour. In favored embodiments, the dried and cured coating composition does not exhibit fogging within 60 seconds after being soaked in 50 C. water for 24 hours. Also described are articles comprising the dried and cured coating composition disposed on a substrate as well as a method a providing an anti-fog coating on a substrate.
