ABSTRACT:
Compounds of the formula I are useful reactive liquid crystal compounds, and can be used in a polymerizable mesogenic mixture, which can be polymerized to an anisotropic polymer. They can be used for the preparation of linear or crosslinked polymers or polymer films for decorative pigments, cosmetics, security applications, active and passive optical elements such as polarizers or retardation films, color filters, scattering displays, adhesives or synthetic resins with anisotropic mechanical properties.
