Abstract:
A process for producing a light-reflective film is disclosed. The process comprises (a) applying a curable liquid crystal composition to a first film having a thickness of d1; (b) drying the applied curable liquid crystal composition to form a cholesteric liquid crystal phase; (c) carrying out a curing reaction of the curable liquid crystal composition and fixing the cholesteric liquid crystal phase to form a lower layer; (d) repeating the set of the steps (a)-(c) three or more times on the lower layer to form a light-reflective multilayer having four or more layers of a fixed cholesteric liquid crystal phase; and (e) transferring the light-reflective multilayer, formed on the first film, onto a second film having a thickness of d2 which is smaller than d1; wherein the first film, fulfilling the condition of formula (1), is used.
