Abstract

1408966 Liquid crystal compositions SUWA SEIKOSHA KK 23 July 1973 [3 Aug 1972] 34942/73 Heading C4X [Also in Divisions H3-H5] Nematic liquid crystal compositions having positive dielectric anisotropy and useful in variable optical activity electro-optic cells (see Divisions H3-H5), are ternary mixtures of Schiff bases, or p,p<SP>1</SP>-substituted azobenzenes or azoxybenzenes, or a binary mixture of p,p<SP>1</SP>- substituted phenyl benzoates, in each case a substituent of one component being nitrile.
