Abstract
PURPOSE: To bichromic pigment for yellow liquid crystal having good orientability in a liquid crystal and excellent bichromic properties, light resistance and solubility, comprising a specified yellow azoic compound.
CONSTITUTION: At least one bichromic pigment for a yollow liquid crystal, selected from yellow azoic compounds (compounds in which two of the side positions of any benzene ring are condensed with a benzene ring to form a naphthalene structure are also included) represented by formulas IWII, wherein R1 is an alkyl, R2 is an alkyl, an alkylcarbonyl, an arylcarbonyl or an alkyloxycarbonyl R3 is a 4W12C alkyl, R4 is nitro, cyano or an alkylsulfonyl and (n) is 1W4.
EFFECT: The pigment has a bichromic ratio of at least eight, and can be effectively used in any liquid crystal including a Schiff type, a biphenyl type and an azoic type. The liquid crysal used may be of any type including a nematic liquid crystal and a cholestericnematic phase transition type liquid crystal.
