A multi-layer coating composites on transparency or glass substrates comprise alternating layers of coatings having high and low refractive index from predominantly inorganic coatings to at least block UV light by a combination of thin film interference and absorption effects. The multilayered coated article has a substrate of clear glass, tinted glass, solar control glass, or colored glass having which is visually transparent to some degree. A first metal-containing predominantly inorganic coating layer that also has some degree of visual transparency and has a refractive index selected from the group of high and low is over the substrate. Over the first coating layer is a second metal-containing predominantly inorganic coating layer that to a degree is visually transparent and has a refractive index opposite from the refractive index of the first coating. Over the second coating layer is a third metal-containing predominantly inorganic coating layer that has a degree of visual transparency and has a refractive index in the range of that of the first coating layer. Additional coating layers can be over, under or interlayered with these first three coating layers to provide different reflective and/or absorption properties. |
