Abstract:
1. A heat ray shielding laminated glass, with an intermediate layer having a heat ray shielding performance interposed between opposed two plate glasses, wherein an intermediate layer having the heat ray shielding performance is obtained by being cured by irradiation of ultraviolet ray, after a dispersion of composite tungsten oxide particles (A1) and/or hexaboride particles (A2) is dissolved into an ultraviolet ray curing resin precursor (E) and thereafter is filled in a gap between the opposed two plate glasses, the composite tungsten oxide particles (A1) and/or the hexaboride particles (A2) being manufactured by the steps of: obtaining slurry by dispersing into a hydrocarbon solvent (B), the composite tungsten oxide particles (A1) expressed by a general formula MxWyOz (wherein M is H, alkali metal, alkali earth metals, rare earth elements, one kind or more elements selected from the group consisting of Mg, Zr, Cr, Mn, Fe, Ru, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Al, Ga, In, Tl, Si, Ge, Sn, Pb, Sb, B, F, P, S, Se, Br, Te, Ti, Nb, V, Mo, Ta, Re, Be, Hf, Os, Bi, and I, wherein W is tungsten, O is oxygen, satisfying 0.001≦x/y≦1, 2.2<z/y≦3.0), and/or the hexaboride particles (A2) expressed by a general formula XB obtaining a dispersion liquid of the composite tungsten oxide particles (A1) and/or the hexaboride particles (A2), with each surface coated with a polymer compound (C) having an ester group, by adding the polymer compound (C) having the ester group, to the slurry and thereafter pulverizing the polymer compound (C); obtaining the dispersion of the composite tungsten oxide particles (A1) and/or the hexaboride particles (A2) by adding a deflocculating agent (D) to the dispersion liquid and thereafter the hydrocarbon solvent (B) is evaporated from the dispersion liquid; and pulverizing the dispersion of the composite tungsten oxide particles (A1) and/or the hexaboride particles (A2) in parallel to vaporizing the hydrocarbon solvent (B) or after vaporizing the hydrocarbon solvent (B), wherein:
