摘要: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.

摘要:Liquid crystalline compositions contain no functional group the synthesis of which is difficult, such as (meth)acrylate and epoxy group and comprise (A) an oxetane compound having an optically active portion, (B) a side chain liquid crystalline polymeric substance having an oxetanyl group, and (C) a photo cation generator and/or a thermal cation generator. The use of the composition can provide a cholesteric-aligned liquid crystal film with excellent alignment retention properties after being fixed in the liquid crystal state and mechanical strength, without employing any complicated step such as photo irradiation under an inert gas atmosphere.
