Abstract

PURPOSE:To provide a color liquid crystal composition containing a specific azo-type or anthraquinone-type dichroic pigment and having excellent contrast, light-resistance and low-temperature stability. CONSTITUTION:The objective composition contains one or more kinds of pigments selected from (A) an azo-type dichroic pigment of formula I (R<1> and R<2> are H, alkyl, etc.; R<3>-R<5> are H, methyl, etc.), (B) an anthraquinone-type dichronic pigment of formula II (R<6> and R<7> are H, alkyl, etc.) and formula III (R<8> and R<9> are H, alkyl, etc.) and (C) an anthraquinone-type dichroic pigment of formula IV (R<10> is H, alkyl, etc.) and formula V (R<11> and R<12> are H, alkyl, etc.).
