Abstract

A heat wave-reflective or electrically conductive laminated structure composed of (A) a shaped solid substrate, (B) a transparent thin layer having a high refractive index in contact with said substrate (A), (C) a transparent heat wave-reflective layer of an electrically conductive metal in contact with said layer (B), and (D) optionally, a transparent thin layer having a high refractive index (D'"'"') in contact with said layer (C) and a transparent top layer (D") in contact with said transparent thin layer (D'"'"'); characterized in that said layer (C) is a layer composed of Ag and Au in which the amount of Au is 3 to 30% by weight based on the total weight of Ag and Au.

Claims

1. A heat wave-reflective or electrically conductive laminated structure composed of

(A) a shaped solid substrate,

(B) a transparent thin layer having a high refractive index in contact with said substrate (A),

(C) a transparent heat wave-reflective layer of an electrically conductive metal in contact with said layer (B), and

(D) optionally, a transparent thin layer having a high refractive index (D'"'"') in contact with said layer (C) and a transparent top layer (D") in contact with said transparent thin layer (D'"'"');

characterized in that said layer (C) is a layer composed of Ag and Au in which the amount of Au is 3 to 30% by weight based on the total weight of Ag and Au.

2. The laminated structure of claim 1 wherein the amount of Au in the layer (C) is 5 to 30% by weight based on the total weight of Ag and Au.

3. The laminated structure of claim 1 wherein the amount of Au in the layer (C) is 10 to 25% by weight based on the total weight of Ag and Au.
