Abstract
A process of preparing a lamination film comprising two or more layers of a fixed cholesteric liquid-crystal phase is disclosed. The process comprises (a) applying a coating liquid of a curable liquid crystal composition comprising a rod-like liquid crystal compound, an alignment-control agent capable of controlling an alignment of the rod-like liquid crystal compound and a solvent to a surface; (b) drying the applied curable liquid crystal composition to form a cholesteric liquid-crystal phase; (c) carrying out a curing reaction of the composition and fixing the cholesteric liquid-crystal phase, thereby to form a lower layer; and (d) repeating the steps (a) to (c) on the lower layer, thereby to form an upper layer; wherein at least a part of the alignment-control agent in the lower layer diffuses into the upper layer.
