Abstract: front page image
(EN)The present invention is a broad-band cholesteric liquid-crystal film which is a cured object obtained from a liquid-crystal composition that comprises a polymerizable mesogenic compound and a chiral agent which is a cyclic compound that changes in torsional force through an intramolecular dimerization reaction.
(FR)La présente invention concerne un film de cristaux liquides cholestériques à large bande qui est un objet durci obtenu à partir d'une composition de cristaux liquides comprenant un composé mésogène polymérisable et un agent chiral qui est un composé cyclique dont la force de torsion change sous l'effet d'une réaction de dimérisation intramoléculaire.
(JA) 本発明は、重合性メソゲン化合物と、分子内二量化反応によってねじれ力が変化する環状化合物であるカイラル剤と、を含有する液晶組成物の硬化物である、広帯域コレステリック液晶フィルムである。
