ABSTRACT:
The present invention is directed to a cathode ray tube having a surface with reduced reflectivity and electrical resistivity and to a method for providing such reduced reflectivity and electrical resistivity. In the method of the invention, a solution of a soluble metallic cation moiety and a silane in an organic solvent is provided. The solution is applied to the surface of a cathode ray tube to provide a coating of the silane and the metallic moiety of the metallic compound on the surface. Thereafter, the cathode ray tube is cured at an elevated temperature for a period of time sufficient to convert the metallic cation moiety to a metal oxide in situ and to provide a metallic oxide in a matrix of siloxane.
