Zusammenfassung:	Coated aluminum material including a base layer of aluminum or an aluminum alloy; a gel film overlying the base layer; and a reflector layer overlying the gel film. The gel film is preferably made by curing a siloxane sol. The reflector layer preferably includes a first silica layer; an aluminum layer; a second silica layer; and a titania layer having a higher index of refraction than the second silica layer. The gel film reduces roughness of the base layer and improves reflectivity.
