AbstractThe present invention concerns novel cholesteric liquid crystalline monomers and combinations thereof with materials that will support formation of a mixture which demonstrates cholesteric liquid crystalline properties. These materials may be formed as coatings, heated or cooled to a desired temperature to cause the cholesteric coating to exhibit a desired optical response, and photopolymerized to essentially fix the optical characteristics of the resulting polymer.
