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. These objects are realized by the interlayer film for laminated glass comprising an adhesive resin, wherein the average particle diameter of tin-doped indium oxide and/or antimony-doped tin oxide is ranging from 0 to 80nm, and the number of the tin-doped indium oxide or antimony-doped tin oxide particles with a particle diameter of not less than 100nm are dispersed not more than 1 per 1 µm2, and also, by a laminated glass produced by interposing said interlayer film for laminated glass between at least a pair of glass sheets having a visible light transmittance rate (Tv) of not less than 65% in the light rays of 380 to 780nm, a solar radiation transmittance rate(Ts) in the light rays of 300 to 2500nm of not more than 80% of the mentioned visible light transmittance rate (Tv), the haze value (H) of up to 1.0% and electromagnetic wave shield (.DELTA.dB ) of not more than 10dB in the wavelength of to 2000 MHz.
L'invention concerne un film intermédiaire pour verre feuilleté comprenant une résine adhésive renfermant des particules d'oxyde d'indium dopées à l'étain ou des particules d'oxyde d'étain dopées à l'antimoine dont la granulométrie moyenne est comprise entre 0 et 80 nm, ces particules étant dispersées de manière que la teneur en particules dont le diamètre est de 100 nm ou plus soit d'une particule par mu m<2> au plus. L'invention concerne également un verre feuilleté comprenant au moins une paire de verres feuilletés et ledit film intermédiaire venant entre la paire de verres feuilletés et formant une structure monobloc avec la paire de verres feuilletés. Le verre feuilleté est caractérisé en outre en ce qu'il fait preuve d'un facteur de transmission de la lumière visible (Tv) à 380-780 nm de 65 % ou plus, d'un facteur de transmission de la lumière solaire (Ts) à 300-2500 nm de 80 % ou moins du facteur de transmission de la lumière visible (Tv) et d'une turbidité (H) de 1,0 % ou moins ou fait preuve d'une propriété d'écran aux ondes électromagnétiques ( DELTA dB) à 10-2000 MHz de 10 dB ou moins.
