Abstract:
A method of producing a laminated glass, comprising the steps of:(a) interposing an interlayer film between first and second glass plates, said interlayer film comprising a polyvinyl butyral or an ethylene-vinylacetate copolymer,said interlayer film comprising functional ultra-fine particles which are dispersed therein and have a particle diameter of up to 0.2 .mu.m, thereby providing insulation against heat caused by solar radiation,said functional ultra-fine particles comprising at least one member selected from the group consisting of an antimony-doped tin oxide, a tin-doped indium oxide, a mixture of Co.sub.2 O.sub.3 and Al.sub.2 O.sub.3, a mixture of TiO.sub.2, NiO, Co.sub.2 O.sub.3 and ZnO, and a mixture of Fe.sub.2 O.sub.3, ZnO and Cr.sub.2 O.sub.3 ; and(b) bonding together said first and second glass plates and said interlayer film.
