Document Type and Number:
Japanese Patent JP7227376
Kind Code:
B2
Abstract:
A new material efficiently attenuating transmission of near-infrared light is provided. A provided near-infrared-shielding material includes a plurality of flaky particles, wherein each of the plurality of flaky particles includes a flaky substrate and a single-layer film formed on a principal surface of the flaky substrate, and the near-infrared-shielding material has a light reflectance of 40% or more between wavelengths of 800 nm and 1400 nm. The flaky substrate is, for example, a glass flake. The glass flake has an average thickness of, for example, 0.6 µm or less. The single-layer film includes, for example, titanium oxide and has an average thickness of, for example, 80 nm to 165 nm.
