Abstract
A low-emissivity multilayer coating includes, in order outward from the substrate, a first layer including a layer containing titanium oxide, a layer containing silicon nitride, or a sublayer layer containing titanium oxide in combination with a sublayer containing silicon 5 nitride, a second layer including Ag, a third layer including at least one layer selected from titanium oxide layers and silicon nitride layers, a fourth layer including Ag, and a fifth layer including silicon nitride, where the color of the coatings can be varied over a wide range by controlling the thicknesses of the layers of titanium oxide, silicon nitride and Ag.
