<p><P>PROBLEM TO BE SOLVED: To provide infrared reflective laminated glass with curved shape which has high transmissivity to visible light, high reflectivity in the infrared region, excellent insulating effect, and transmits a variety of radio waves. <P>SOLUTION: In the laminated glass, a plastic film is sandwiched between two resin intermediate films, and an infrared reflective film is formed in the plastic film by alternately laminating resin films having different refractive indexes. The plastic film in which the infrared reflective film is formed meets any of the following conditions; (A) thermal shrinkage of 0.5 to 3% in 90 to 150°C temperature range, (B) elastic modulus of 30 to 2,000 MPa in 90 to 150°C temperature range, and (C) the rate of elongation of the plastic film is 0.3% or less when 10 N tensile force per 1 m width of the plastic film is exerted in 90 to 150°C temperature range. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
