PROBLEM TO BE SOLVED: To provide a heat ray shielding dispersion capable of forming a transparent film with low haze and having excellent heat ray shielding effect.SOLUTION: The dispersion includes a heat ray shielding material powder, a plasticizer, an alcohol, a dispersion protecting agent and a dispersion stabilizer, and the dispersion for forming the heat ray shielding film contains 0.05-10.0 mass% of water relative to the content of the heat ray shielding material powder. Preferably, in the dispersion for forming the heat ray shielding film, the heat ray shielding material power is a mixed powder of an ATO powder and an ITO powder, a mixed powder of an ATO powder or an ITO powder or an ITO powder and an AlOpowder, a mixed powder of an ITO powder and a ZnO powder, or a mixed powder of an ITO powder and a TiOpowder and an ITO powder and a SiOpowder, the visible light transmittance (%Tv) is 84% or higher, the solar radiation transmittance (%Ts) is 64% or lower, and the haze is 0.65% or lower. |
