Title:
赤外光反射板、赤外光反射性合わせガラス、並びにコレステリック液晶層を有する積層体及び合わせガラス
Document Type and Number:
Japanese Patent JP5259501
Kind Code:
B2
Abstract:
To provide an infrared-light reflective plate having the improved selective reflectivity characteristics. Disclosed is an infrared-light reflective plate reflecting an infrared-light of equal to or longer than 700nm comprising a substrate, and, on at least one of surfaces of the substrate, at least four light-reflective layers, X1, X2, X3 and X4, formed of a fixed cholesteric liquid crystal phase, and disposed in this order from the substrate, wherein the reflection center wavelengths of the light-reflective layers X1 and X2 are same with each other and are » 1 (nm), and the two layers reflect circularly-polarized light in opposite directions; the reflection center wavelengths of the light-reflective layers X3 and X4 are same with each other and are » 2 (nm), and the two layers reflect circularly-polarized light in opposite directions; and » 1 <» 2 is satisfied.
