Touch screen displays and other coated articles demonstrating antiglare properties are provided. A method of forming an antiglare coating on a substrate is also provided, and may be used to prepare the coated articles. The method comprises: (a) heating the substrate to a temperature of at least 100 °F (37.8 °C) to form a heated substrate; (b) applying a curable film-forming composition on at least one surface of the heated substrate to form a substrate coated with a sol-gel layer; and (c) subjecting the coated substrate to thermal conditions for a time sufficient to effect cure of the sol-gel layer. The curable film-forming composition comprises:
(i) a silane;
(ii) a mineral acid; and
(iii) a solvent;
wherein the weight ratio of mineral acid to silane is greater than 0.008:1 and the curable film-forming composition has a solids content of less than 10 percent by weight.
