US Patent 10358384 Solar control coatings with discontinuous metal layer

An architectural transparency includes a substrate, a first dielectric layer formed over at least a portion of the substrate, a subcritical metallic layer formed over at least a portion of the first dielectric layer, a primer layer formed over the subcritical metallic layer and, a second dielectric layer formed over at least a portion of the primer layer. The primer layer contains an oxygen-capturing material that can be sacrificed during a deposition process or heating process to prevent degradation of the subcritical metallic layer.
