Abstract
The present invention relates to a laminated glass having an interlayer film between at least two transparent glass platy bodies. Functional ultra-fine particles of a particle diameter of not greater than 0.2 .mu.m are dispersed in the interlayer film. The functional ultra-fine particles comprise a single substance of metal, oxide, nitride, 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 and 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 selectively reflects a near-infrared ray and has a sheet resistivity ranging from 1 k.OMEGA./.quadrature. to 10 G.OMEGA./.quadrature. is formed on at least one surface of the interlayer film or at least one transparent glass platy body.
