    • 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.
    • 本发明提供了形成胆甾型液晶层的方法,其包括形成胆甾醇型液晶组合物,将胆甾型液晶组合物沉积在基板上,并且在约90℃或低于约90℃的温度下开始干燥胆甾型液晶组合物,使得 胆甾型液晶组合物残留有至少80%的固体。 本发明还提供了形成胆甾型液晶层的方法,其包括形成胆甾醇型液晶组合物,将胆甾型液晶组合物沉积在基材上,并且在约90℃或更低的温度下最初干燥胆甾型液晶组合物, 其中使用提供很少或没有气流的技术来实现干燥。 本发明还提供一种胆甾型液晶组合物,其包括至少一种胆甾型液晶前体和1,3-二氧戊环。
