Title (EN) POWDER MIXTURE
(FR) MÉLANGE DE POUDRES
(JA) 粉体混合物
Abstract:
(EN) The present invention addresses the problem of providing a powder mixture using a polymerizable liquid crystal compound having excellent fluidity and handling properties that poses little risk of fire caused by solvent flammability, that does not undergo changes in the appearance of the contents due to precipitation or crystallization during low-temperature storage, that does not change in composition due to volatilization of the solvent during long-term storage or due to leakage during long-term storage or transport, and that is not viscous like a nematic liquid crystal composition. Also provided is a nematic liquid crystal composition that uses the powder mixture, a solution composition, a cured product, an optical film, and a display element.
(FR) Le problème de la présente invention concerne un mélange de poudres utilisant un composé cristallin liquide polymérisable présentant une excellente fluidité et d'excellentes propriétés de manipulation, qui présente un faible risque d'incendie provoqué par l'inflammabilité du solvant, dont l'apparence du contenu ne subit pas de changements en raison d'une précipitation ou d'une cristallisation pendant le stockage à basse température, dont la composition ne change pas en raison d'une volatilisation du solvant pendant un stockage longue durée ou en raison d'une fuite pendant un stockage longue durée ou un transport et qui n'est pas visqueux comme une composition de cristaux liquides nématiques. L'invention concerne également une composition de cristaux liquides nématiques qui utilise le mélange de poudres, une composition de solution, un produit durci, un film optique et un élément d'affichage.
(JA) 本発明の課題は、溶剤引火性に起因する火災に対する危険性が少なく、低温保存時に内容物が析出や結晶化などによる外観の変化を起こすことがなく、長期保管時に溶剤が揮発、あるいは、長期保管時や運搬時に漏洩することによって組成が変化することがなく、また、ネマチック液晶組成物のように粘凋ではなく、流動性があり、かつ、取扱性に優れた重合性液晶化合物を用いた粉体混合物を提供することである。また、当該粉体混合物を用いたネマチック液晶組成物、溶液組成物、硬化物、光学フィルム、表示素子を提供することにある。
