BLACK DICHROIC DYE

Described is a black dichroic dye composition comprising 2 or more dyes, wherein at least one dye, generally a red dye and optionally a yellow dye, conforms to the formula A and at least one dye, usually a blue dye, conforms to the formula B Ar1-N=N-[Ar2-N=N-]qAr3-N=N-Ar4 (B) with symbols as defined in present claims. The dye composition is well suited for combination with liquid crystal material for use, inter alia, as polarizing film and/or in liquid crystal displays, showing, inter alia, high dichroic ratio and excellent compatibility with the LC material.
