1. An anti-reflection high conductivity multi-layer coating for CRT products comprising first, second, third and fourth consecutive layers with the first layer being the nearest layer to a substrate, said layers being created by a combination process including a vacuum coating and a wet coating;

  • said first layer being positioned between said substrate and said second layer and comprising a conductive oxide material having a refractive index between 1.85 to 2.1 at a wavelength of 520 nm, said first layer having a physical thickness of 20-80 nm, and being produced by vacuum sputtering coating;

    said second layer being positioned on said first layer and comprising an oxide material having a refractive index within the approximating range of 1.45 to 1.50 at a wavelength of 520 nm and a physical thickness of 10 nm to 50 nm, said second layer being produced by vacuum sputtering coating;

    said third layer being positioned on said second layer and comprising a high chemical resistance oxide material having a refractive index within 1.85 to 2.2 at a wavelength of 520 nm and a physical thickness of 40.0-60.0 nm, said third layer being produced by vacuum sputtering coating; and

    said fourth layer being positioned on said third layer and comprising an oxide material having a refractive index within 1.45 to 1.55 at a wavelength of 520 nm and a physical thickness of 60-120 nm, said fourth layer being produced by wet coating.
