    摘要： A method of slide coating that includes providing a first fluid, wherein the first fluid includes at least one solvent, at least one single unit polymeric precursor or a combination thereof; providing a second fluid, wherein the second fluid includes multi unit polymeric precursors; flowing the first fluid down a first slide surface, to create a first fluid layer on the first slide surface, the first slide surface being positioned adjacent a substrate; flowing the second fluid down a second slide surface, the second slide surface positioned relative to the first slide surface such that the second fluid flows from the second slide surface to above the first slide surface onto the first fluid layer to create the second fluid layer on the first slide surface; coating the substrate with the first and second fluid by flowing the first fluid layer and the second fluid layer from the first slide surface to the substrate forming first and second coated layers; moving the substrate; and at least partially curing the first coated layer, the second coated layer, or some combination thereof.

    摘要： An optical body includes a substrate and a cholesteric liquid crystal layer disposed on the substrate. The cholesteric liquid crystal layer has a non-uniform pitch along a thickness direction of the layer and comprises a crosslinked polymer material that substantially fixes the cholesteric liquid crystal layer. The crosslinking hinders diffusion of cholesteric liquid crystal material within the cholesteric liquid crystal layer. In other methods of making an optical body, a reservoir of chiral material is provided during the process over a first cholesteric liquid crystal layer to diffuse into the layer and provide a non-uniform pitch. Alternatively, two coating compositions can be disposed on a substrate where the material of the first coating composition is not substantially soluble in the second coating composition.
