    摘要： The invention relates to a process of preparing a multilayer cholesteric film comprising two or more layers of polymerized cholesteric liquid crystal (CLC) material with planar orientation, with the cholesteric helix axis oriented substantially perpendicular to the plane of the layer, wherein that the cholesteric helical pitch of adjacent layers is varied by controlled migration of a non-polymerized chiral material between the layers, to a multilayer cholesteric film obtainable by such a process, and to the use of the process and a multilayer cholesteric film thereby prepared in optical elements such as polarizers, compensators, alignment layers, color filters or holographic elements, in cosmetics and liquid crystal pigments, for decorative and security applications.

    摘要： The invention relates to a process of preparing a multilayer cholesteric film comprising two or more layers of polymerized cholesteric liquid crystal (CLC) material with planar orientation, with the cholesteric helix axis oriented substantially perpendicular to the plane of the layer, wherein during preparation of the single layers the migration of unpolymerized material between adjacent layers is minimized, to a multilayer cholesteric film obtainable by such a process, and to the use of the process and a multilayer cholesteric film thereby prepared in optical elements such as polarizers, compensators, alignment layers, color filters or holographic elements, in cosmetics and liquid crystal pigments, for decorative and security applications.
