Light modulating materials |
摘要 |
A light modulating material having an excellent energy saving effect as window materials and others which comprises as a main component member a laminate wherein a liquid crystalline material is placed over at least one light transmitting substrate, said laminate having properties of a light transmittance of not less than 50% at a wavelength of 400-750 nm at an overall temperature from not lower than 273K to not higher than 313K, a light transmittance of not less than 60% at a wavelength of 750-2000 nm at an overall temperature from not lower than 273K to low than 288K and a light transmittance of not more than 40% and a light reflectance of not less than 50% at a wavelength of 750-2000 nm at a wavelength of 750-2000 nm at an overall temperature from not lower than 298K to not higher than 313K.
