Abstract:
1. A laminated glass having an interlayer film between at least two transparent glass platy bodies, wherein: functional ultra-fine particles of a particle diameter of not greater than 0.2 μm are dispersed in the interlayer film, the functional ultra-fine particles comprise a single substance of metal, metal oxide, metal nitride, metal sulfide or Sb- or F-doped substance of Sn, Ti, Si, Zn, Zr, Fe, Al, Cr, Co, Ce, In, Ni, Ag, Cu, Pt, Mn, Ta, W, V or Mo, or a composite selected from at least two of these, or a mixture containing an organic resin substance in the single substance or composite, or a coated substance coated with the single substance or composite, or an antimony-doped tin oxide and/or tin-doped indium oxide, an infrared-reflective film that has a sheet resistivity ranging from 1 kΩ/□ to 10 GΩ/□ is formed on at least one surface of the interlayer film, and the infrared-reflective film is (a) a single layer made of CrO, NiCrO or a stainless steel oxide, or (b) a laminate of three layers having a first layer formed on the at least one surface of the interlayer film, a second layer formed on the first layer, and a third layer formed on the second layer, the first, second and third layers of the laminate respectively being (i) ZnO, a stainless steel and ZnO, (ii) ZnO, a stainless steel nitride and ZnO, (iii) ZnO, CrN and ZnO, (iv) SnO, CrN and SnO, (v) SiO, Si and SiO, (vi) Si
