Abstract

There is provided a composite tungsten oxide particle dispersion polycarbonate resin composition containing composite tungsten oxide particles expressed by a general formula MxWyOz, metal salt, and polycarbonate resin, wherein the metal salt is a salt of one or more kinds of metal elements selected from Mg, Ni, Zn, In, and Sn.

First claim

The invention claimed is:

1. A composite tungsten oxide particle dispersion polycarbonate resin composition containing composite tungsten oxide particles expressed by a general formula MxWyOz (wherein M is one or more kinds of elements selected from H, alkali metal, alkali earth metal, rare earth elements, 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, W is tungsten, O is oxygen, satisfying 0.001≦x/y≦1, 2.2≦z/y≦3.0), metal salt, and polycarbonate resin,
wherein the metal salt is a salt of one or more kinds of metal elements selected from Mg, Ni, Zn, In, and Sn, and
an addition amount of the metal salt is 0.1 to 50 parts by weight based on 100 parts by weight of the composite tungsten oxide particles.

2. The composite tungsten oxide particle dispersion polycarbonate resin composition according to claim 1 , wherein the metal salt is or more kinds of selected from the group consisting of carboxylate, carbonyl complex salt, carbonate, phosphate, perchlorate, hypochlorite, chlorite, chlorate, and hydrochloride.

3. A heat-ray shielding molding, wherein the composite tungsten oxide particle dispersion polycarbonate resin composition of claim 2 is diluted, melted, and kneaded by polycarbonate resin or a different kind of thermoplastic resin having compatibility with polycarbonate resin, and molded into a specific shape.

4. A heat-ray shielding molding, wherein the composite tungsten oxide particle dispersion polycarbonate resin composition of claim 1 is diluted, melted, and kneaded by polycarbonate resin or a different kind of thermoplastic resin having compatibility with polycarbonate resin, and molded into a specific shape.

5. A heat-ray shielding laminate, wherein the heat-ray shielding molding of claim 4 is laminated on other transparent molding.
