    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).
