Durable coating composition, process for producing durable, antireflective coatings, and coated articles

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.
