  • Patent number: 8449983
    Abstract: It is an object of the present invention to provide an interlayer film for laminated glass containing gallium-doped zinc oxide fine particles as heat shielding fine particles and exhibiting a high transparency and an excellent heat shielding performance. The present invention is an interlayer film for laminated glass, which comprises gallium-doped zinc oxide fine particles, a plasticizer, a dispersant, and a thermoplastic resin, wherein the gallium-doped zinc oxide fine particles have a hexagonal crystalline structure and a c-axis crystal lattice constant of 0.5207 nm or more, and a visible light transmittance TV of 70% or more and an infrared transmittance TIR of less than 75% are obtained from measurement by the method according to JIS R 3106 performed on laminated glass obtained by interposing the interlayer film for laminated glass between a pair of 2.5 mm-thick clear glass sheets.
