发明名称 FLUESSIGKRISTALLINE MISCHUNGEN
摘要 The invention relates to crystalline-liquid 4-(3'-n-alkylcyclopentyl)carboxylic acid esters of the general Formula I <IMAGE> wherein <IMAGE> X and R have the significance stated in the documents of the description. The compounds in accordance with the invention are added alone or in mixture in quantities of 0.5 to 80 mol % to liquid-crystalline basic mixtures. Liquid-crystalline mixtures are obtained with low anisotropy of the refractive index and high clarification temperature for electro-optical arrangement for modulation of the transmitted or reflected light and for the coloured or monochrome display of digits, characters and moving or unmoving images.
