摘要:
A low viscosity, short pitch, cholesteric liquid crystal composition consisting of an alkali cromoglycate dissolved in water or water with a polar solvent, together with an optically active solute in sufficient concentration to render the cromoglycate cholesteric. Suitable compositions will reflect light in the visible spectrum and may be magnetically, electrically, or thermally addressed to produce optical effects therein.
