摘要： A coating composition, a process for the preparation of antireflective coatings and coated articles. The coating process comprises: (a) coating host material with coating composition consisting essentially of: (1) about 20 to 70 weight percent of a silane monomer mixture comprising a glycidoxyalkylalkoxysilane and an alkylalkoxysilane(s); (2) about 0 to 40 weight percent of tetra(C1-C4) alkoxysilane; (3) about 0 to 10 weight percent of fluorinated silane(s); (4) about 1 to 8 weight percent of a water-soluble polymer; (5) a leveling amount of nonionic surfactant; (6) a solvating amount of a lower aliphatic alcohol; (7) a catalytic amount of water-soluble acid; and (8) water; (b) curing the coated host material; (c) treating the cured coating with an aqueous acidic solution; (d) contacting the treated coating with an aqueous leaching solution; and (e) curing the product of step d.

摘要： The invention describes a composition for producing durable coatings and a process for preparing a single-layer broad band antireflective coating on solid substrates, such as glass, ceramics, metals, and organic polymeric materials. The coating composition comprises, in combination, acid catalyzed hydrolysis and condensation products of water-silane monomer mixture and a film forming amount of a polymer having functional groups selected from amino, hydroxy and carboxy, hydroxy and amino, amino and carboxy, and amino, hydroxy and carboxy. The described process comprises applying the aforesaid coating composition (or an acid catalyzed sol-gel coating composition) substantially free of preformed oxide sol and water soluble metal salt to the surface of a solid substrate, curing the applied coating, and treating the cured coating with an aqueous electrolyte solution for a time sufficient to produce a coating having graded porosity which is antireflective over a broad band of the visible spectrum.
