Title:
INFRARED LIGHT REFLECTOR, INFRARED LIGHT REFLECTING LAMINATED GLASS, AND LAMINATED GLASS AND LAMINATE HAVING CHOLESTERIC LIQUID CRYSTAL LAYERS
Document Type and Number:
WIPO Patent Application WO/2010/143684
Kind Code:
A1
Abstract:
Provided is an infrared light reflector exhibiting improved selective reflection properties. The infrared light reflector is provided with a substrate and at least four light reflecting layers (X1, X2, X3, X4), which is obtained by immobilizing a cholesteric liquid crystal phase, on at least one surface of the substrate in the order from X1 to X4. The light reflecting layers (X1, X2) both have a reflection center wavelength of λ1 (nm) and reflect circularly-polarized light having inverse propagation directions, and the light reflecting layers (X3, X4) both have a reflection center wavelength of λ2 (nm) and reflect circularly-polarized light having inverse propagation directions; λ2 is greater than λ1.
