Abstract

The present invention relates to a method of interleaving a support comprising providing a support, applying a curable material to a side of the support, applying an interleaving material to the support so as not to be in contact with the curable material, and winding the support to produce a continuous gap between the side of the support opposite the coated side of the support. The present invention also includes a roll of liquid crystalline material comprising a support having thereon a curable material and an interleaving material, wherein the interleaving material is not in contact with the curable material on the support, and wherein the support is wound to form a roll.
