  • Patent number: 7396583
    Abstract: A transparent and conductive laminate that is substantially decreased in reactive defects, and a display filter, a heat-ray reflecting film and an electromagnetic wave-shielding film comprising the laminate are provided. The laminate includes a transparent substrate, a transparent conductive thin-film layer containing silver, and a protective layer containing a binder material and inorganic fine particles, wherein the transparent conductive thin-film layer is in contact with the protective layer. The generation of reflective defects can be outstandingly reduced. Therefore, a laminate superior in electromagnetic wave-shielding ability, heat-ray reflecting ability and visibility for a long period of time and products comprising the laminate can be obtained.
    Type: Grant

  • Patent number: 6104530
    Abstract: Transparent laminates which have high transparency and, moreover, excellent electromagnetic shielding characteristics and near-infrared cutting-off characteristics, and optical filters for displays using these transparent laminates. These transparent laminates are formed by laminating a transparent electrically conductive layer composed of high-refractive-index transparent film layers (B) and metal film layers (C) consisting of silver or a silver-containing alloy on one major surface of a transparent substrate (A) in such a way that a repeating unit comprising a combination of one high-refractive-index transparent film layer (B) and one metal film layer (C) is laminated three times or more, and further laminating one high-refractive-index transparent film layer (B) thereon. The transparent laminate has a sheet resistance of not greater than 3 .OMEGA./sq., a visible light transmittance of not less than 50%, and a light transmittance of not greater than 20% in a wavelength region longer than 820 nm.

  • Patent number: 5911899
    Abstract: A transparent heater panel having a transparent substrate, a transparent conductive layer formed on the transparent substrate, electrodes formed on the transparent conductive layer and a transparent protective layer formed on the transparent conductive layer except portions reserved for the electrodes with the end faces of the transparent conductive layer corrosion treated with a transparent protective plastic member or an anticorrosive; and a process for producing the same. The heater panel has improved durability against pollutants, environmental durability, reliability and light transmission.
