摘要： Curable film-forming sol-gel compositions that are essentially free of inorganic oxide particles are provided. The compositions contain: a tetraalkoxysilane; a solvent component; and non-oxide particles, and further contain either i) a mineral acid or ii) an epoxy functional trialkoxysilane and a metal-containing catalyst. Coated articles demonstrating antiglare properties are also provided, comprising: (a) a substrate having at least one surface; and (b) a cured film-forming composition applied thereon, formed from a curable sol-gel composition comprising a silane and non-oxide particles. A method of forming an antiglare coating on a substrate is also provided. The method comprises: (a) applying a curable film-forming sol-gel composition on at least one surface of the substrate to form a coated substrate; and (b) subjecting the coated substrate to thermal conditions for a time sufficient to effect cure of the sol-gel composition and form a coated substrate with a sol-gel network layer having anti-glare properties.
