Summary: | Methods of making an optical body include coating a mixture including a first cholesteric liquid crystal polymer, a second cholesteric liquid crystal monomer, a second cholesteric liquid crystal polymer formed from a portion of the second cholesteric liquid crystal monomer, and a solvent on a substrate. The first cholesteric liquid crystal polymer is different than the second cholesteric liquid crystal polymer. Then, forming from the mixture an optical body including a first layer, a second layer, and a third layer disposed between the first and second layer. The first layer includes a majority of the first cholesteric liquid crystal polymer. The second layer includes a majority of a second cholesteric liquid crystal monomer. The third layer includes the second cholesteric liquid crystal polymer. |
