摘要： Liquid crystal pigments comprising at least one layer of liquid crystalline polymer material with a helically twisted molecular structure wherein the helical axis is oriented substantially perpendicular to the plane of the layer and which show reflection of circularly polarized light, some prepared in which the bandwidth of the reflected wavelength band is at least 100 nm. These pigments are suitable for use in reflective films or coatings for decorative applications, cosmetic compositions, and pharmaceutical compositions, optical elements, and security applications.
