Heat wave-reflective or electrically conductive laminated structure

In 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 of at least 1.6 with respect to visible light in contact with one or both surfaces of a layer (C) below, wherein when the layer (B) is provided on both surfaces of the layer (C), it can, at one surface, be a transparent thin layer (B) whose refractive index is lower than that of 1.6 with respect to visible light,
• (C) a transparent heat wave-reflective thin layer of an electrically conductive metal in contact with the substrate (A) or with the transparent thin layer (B), and wherein the laminated structure can also contain the following layer:
• (D) a transparent top layer;
• the improvement wherein said layer (C) is a layer composed of at least about 50% by weight of Ag, about 3 to about 30% by weight of Au and about 0.5 to about 30% of Cu, the amounts being based on the total weight of Ag, Au and Cu.
