Abstract

PURPOSE:To improve the contrast, light-shielding property, low-temp. stability, and light fastness, by incorporating in a liq. crystal compsn. at least one dichroic pigment selected from azo dichroic pigments and two particular anthraquinone dichroic pigments. CONSTITUTION:At least one dichroic pigment (B) selected from azo dichroic pigments (a) of formula I [wherein R<1> and R<2> are each H, (alkoxy)alkyl, alkoxy, or arylmethyl; R<3>-R<5> are each H, CH3, OCH3, or a halogen, provided that R<4> and R<5> may be combined to form an aromatic ring], anthraquinone dichroic pigments (b) of formulae II and III [wherein R<6>-R<9> are each H, alkyl, (satd.) cycloalkyl, aryl, alkoxy(alkyl), or aralkyl], and anthraquinone dichroic pigments of formulae IV and V (wherein R<10>-R<12> are each R<6>) is dissolved in a liq. crystal substance (A) of formulae VI-IX [wherein R<13> and R<14> are each (alkoxy) alkyl, (alkoxy)alkylphenyl, cyanophenyl, or halogen].
