摘要:
The invention provides methods of forming a cholesteric liquid crystal layer that include forming a cholesteric liquid crystal composition, depositing the cholesteric liquid crystal composition onto a substrate, and initially drying the cholesteric liquid crystal composition at a temperature at or below about 90 °C so that the cholesteric liquid crystal composition has at least 80 % solids remaining. The invention also provides methods of forming a cholesteric liquid crystal layer that include forming a cholesteric liquid crystal composition, depositing the cholesteric liquid crystal composition onto a substrate, and initially drying the cholesteric liquid crystal composition at a temperature at or below about 90 °C, wherein the drying is accomplished using a technique that provides little or no airflow. The invention further provides a cholesteric liquid crystal composition that includes at least one cholesteric liquid crystal precursor and 1,3-dioxolane.
