HEAT-RAY SHIELDING FILM, MANUFACTURING METHOD THEREFOR, LAMINATED GLASS, AND HEAT-RAY SHIELDING MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a heat-ray shielding film having high transparency and heat-shielding capability.SOLUTION: A heat-ray shielding film comprises a substrate having at least two light-reflective layers X1, X2 obtained by fixing cholesteric liquid crystal phases and an infrared absorbing layer containing composite tungsten oxide microparticles. The light-reflective layer X1 and the light-reflective layer X2 reflect circularly polarized light of opposite polarization directions and have substantially identical central reflection wavelengths in a range of 800 to 1100 nm. All light-reflective layers obtained by fixing cholesteric liquid crystal phase have reflectances of 80% or more.
