Abstract:
A heat wave-reflective or electrically conductive substantially transparent sheet comprising a transparent flexible polyester sheet solid substrate, a transparent first boundary layer of dielectric having an index of refraction greater than 1.75 and a thickness of from about 100 to 1500 .ANG. on said substrate, a transparent gold-clad silver layer having a sputter-deposited 50 .ANG. to 400 .ANG. silver layer consisting of silver with not more than 0.5% by weight of other metals clad on both sides or on its side adjacent to the transparent first boundary layer with a sputter-deposited 0.3 .ANG. to 50 .ANG. layer consisting of gold or an alloy of silver and at least 30% gold on said transparent first boundary layer, and a transparent second boundary layer of dielectric having an index of refraction greater than 1.75 and a thickness of from about 100 to 1500 .ANG. on said gold-clad silver layer.
