Solar control coatings providing increased absorption or tint
A coated article includes a substrate, a first dielectric layer, a subcritical metallic layer having discontinuous metallic regions, a primer over the subcritical layer, and a second dielectric layer over the primer layer. The primer can be a nickel-chromium alloy. The primer can be a multilayer primer having a first layer of a nickel-chromium alloy and a second layer of titania.
