METHOD OF FORMING AN ANTI-GLARE COATING ON A SUBSTRATE
First Claim
1. A method of forming an anti-glare coating on a substrate comprising:
- (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 sol-gel composition on at least one surface of the heated substrate, to form a coated substrate with a sol-gel network layer having a surface roughness;
wherein the sol-gel network layer is essentially free of inorganic oxide particles and wherein the curable film-forming sol-gel composition comprises;
(i) a tetraalkoxysilane;
(ii) an epoxy functional trialkoxysilane;
(iii) a metal-containing catalyst; and
(iv) a solvent component; and
(c) subjecting the coated substrate to conditions for a time sufficient to effect cure of the sol-gel layer and form an anti-glare, coated article.

Abstract
A method of forming an anti-glare coating on a substrate is provided. 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 sol-gel composition on at least one surface of the heated substrate, to form a coated substrate with a sol-gel network layer having a surface roughness; and (c) subjecting the coated substrate to conditions for a time sufficient to effect cure of the sol-gel layer and form an anti-glare, coated article. The sol-gel network layer is essentially free of inorganic oxide particles and comprises:
- (i) a tetraalkoxysilane;
- (ii) an epoxy functional trialkoxysilane;
- (iii) a metal-containing catalyst; and
- (iv) a solvent component. Coated articles prepared by the method above and demonstrating anti-glare properties are also provided.
