摘要:
The invention provides a specific pyrazole disazo dye which is a yellow dye having excellent solubility in nonpolar solvents, in particular, hydrocarbon solvents, and having a high extinction coefficient. The dye preferably is preferably a pyrazole disazo dye represented by the following general formula (I): (wherein R1 represents a C2-C10 alkyl group; R2 represents a C3-C10 alkyl group; the six-membered ring A represents a phenyl group which may have a substituent; and the six-membered ring B represents a phenylene group which may have a substituent).

摘要:
Provided are a dichroic dye composition in which a solubility of the dichroic dye with respect to liquid-crystal is sufficiently high and a wavelength dispersion of absorbance is small in a wide wavelength range, and a black guest-host liquid-crystal composition indicating high order parameters using such a dichroic dye composition and a liquid-crystal element having high contrast. The dichroic dye composition includes at least one dichroic dye selected from Group (I) shown below, at least one dichroic dye selected from Group (II) shown below, and at least one dichroic dye selected from Group (III) shown below.
