Abstract
A polymerizable liquid crystalline composition comprises a side chain liquid crystalline polymer obtained by radical-copolymerizing a (meth)acrylic compound has an optically active site and a (meth)acrylic compound having an oxetanyl group, and a cation generator and thus have no functional group the synthesis of which is difficult, such as an epoxy group. The use of the polymerizable liquid crystalline composition provides a cholesteric liquid crystal film which is excellent in a capability of retaining the orientation after being aligned and fixed in a liquid crystal orientation and in mechanical strength without the necessity of a complicated operation such as photo irradiation under an inert gas atmosphere.
