  • Patent number: 7252887
    Abstract: The object of the present invention is to provide an interlayer film for laminated glass which exerts excellent heat insulation or electromagnetic wave transmittance and which is suitable for producing a laminated glass having excellent fundamental performance characteristics required for the laminated glass, such as transparency, especially good haze, appropriate bond strength between an interlayer film and glass, penetration resistance, impact absorption, weather resistance, and so on. Also, the object of the present invention is to provide a laminated glass produced by using the above-mentioned interlayer film.
    Type: Grant

  • Patent number: 7160624
    Abstract: An object of the present invention is to provide an interlayer film for a laminated glass and a laminated glass, which are superior in transparency, heat shield property, electromagnetic wave permeability and weatherability. The present invention is directed to an interlayer film for a laminated glass, wherein a laminated glass, produced by interposing the film between two sheets of glass selected from the group consisting of clear glass, green glass and high heat ray absorbing glass, has an electromagnetic wave shielding performance of 10 dB or less at a frequency of 0.1 to 10 MHz and 2 to 26.5 GHz, a haze of 1.0% or less, a visible light transmittance of 70% or more and a solar radiation transmittance of 85% or less of the visible light transmittance in a wavelength region of 300 nm to 2100 nm.
