Composition and method for a coating providing anti-reflective and anti-static properties

Abstract

Coating solutions having anti-reflective and anti-static properties, a coating derived therefrom, a substrate coated with the coating and methods for their preparation. A coating includes a sol-gel alkoxide polymeric material and a conductive colloidal metal compound material.

What is claimed is:  
     
         1 . A method for preparing a coating solution comprising: 
 subjecting a solution of an alkoxide to hydrolyzation and condensation in a reaction system;    aging the solution to form a sol-gel reaction product; and    diluting the reaction product.    
     
     
         2 . The method of  claim 1 , wherein the alkoxide comprises one of the general formula:  
       M(OR) x   wherein M is selected from at least one of the group consisting of Si, Ti, B, Al, and Zr,    wherein R is an alkyl group having 1-8 carbons and x is the valence state of the cation.    
     
     
         3 . The method of  claim 1 , wherein the aging comprises 1 to 24 hours at 50° C.
