Abstract
A coated article includes a substrate, a first dielectric layer, a first metallic layer, a second dielectric layer, a second metallic layer, a third dielectric layer, a third metallic layer, a fourth dielectric layer, a fourth metallic layer and a fifth dielectric layer. At least one of the metallic layers is a discontinuous metallic layer having discontinuous metallic regions. An optional primer is positioned over any one of the metallic layers. Optionally a protective layer is provided as the outer most layer over the fifth dielectric layer.
