LAYER OR ARTICLE COMPRISING POLYMER PARTICLES

摘要

The invention relates to a layer or article comprising cholesteric liquid crystal polymer particles, which are optionally dispersed in a continuous phase, to cholesteric polymer particles for use in such a layer or article, to methods of preparing such a layer or article, and to the use of such a layer or article as optical element, in windows or electrooptical devices like liquid crystal displays (LCDs).
