Due to the increased glazed area of modern vehicles, especially the large panoramic glass roofs, we have seen a substantial growth in the use solar control glass and coatings. The solar glass compositions and coatings are expensive to manufacture. While solar coatings are more efficient than compositions, they typically cannot be used on monolithic glazing as they are not durable. They must be applied to one of the surfaces on the inside of a laminate. Most of these products also introduce an undesirable color shift. The invention provides a coating that can be used on glass to produce a laminated or monolithic glazing with a neutral gray solar control coating which also has anti-reflective properties and low emissivity.
