Patent ID: 7351448

Claim:
A process of coating metal or metallic surfaces comprising: providing at least one metal having a patterned outer surface exhibiting an optical reflection greater than about 40%; providing at least one anti-reflective coating material having specific light scattering properties, selected from the group of electrically conductive materials consisting of platinum black and nickel black; said anti-reflective coating material(s) having effective reflectivity in the range from about 10% to about 60%; said effective reflectivity being the average reflectivity over a wavelength range from about 0.1 μm to about 1000 μm; and depositing said anti-reflective coating material(s) onto said patterned outer surface(s) of each said metal, wherein said anti-reflective coating material(s) having a thickness of about 10 nm to about 2 μm conforms to said patterned outer surface(s) of each said metal.
