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 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 may, at one surface, be a transparent thin layer (B) whose refractive index is not high, (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 (D) optionally, 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. |
