A polymerizable liquid crystal compound having no functional group which is difficult to synthesize, such as an epoxy group, comprising: a side chain type liquid crystal polymer material obtained by radical copolymerization of a (meth) acryl compound having an optically active site and a (meth) acrylic compound having an oxetanyl group, and The polymeric liquid crystal composition containing a cation generator is provided, and by using this polymeric liquid crystal composition, the orientation maintenance ability and mechanical strength after liquid crystal orientation fixation are not required, without requiring complicated processes, such as light irradiation in an inert gas atmosphere. An excellent cholesteric oriented liquid crystal film is provided.n n n Polymerizable liquid crystal composition, optically active site, oxetanyl group, (meth) acryl compound, radical copolymerization, cholesteric alignment liquid crystal film |
