  • Patent number: 4320169
    Abstract: 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.
    Type: Grant

  • Patent number: 4234654
    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.
