/Heat-treatable Coating With Blocking Layer Having Reduced Color Shift
Abstract

A coated article includes a substrate with a first surface and a second surface and a functional coating applied over the first surface or the second surface. The functional coating includes a blocking layer over at least a portion of the substrate; a metallic layer over at least a portion of the blocking layer; and a top layer over at least a portion of the metallic layer. The coated article has an optical color shift, as measured by ΔEcmc, of no more than 4.5 after tempering.
