    摘要： The present invention is directed to a disperse dye of formula (1) Wherein, X, Y and Z are, independently, hydrogen, halogen, cyano, nitro or SO2F; Wherein at least one of X, Y and Z is SO2F. R1 is hydrogen, methyl, hydroxyl or NHR4; R2 is hydrogen, chloro or methoxy; R3 is hydrogen, (C1-C4)-alkyl or -CH2(CH2)nCOOCH2CN; R5 is hydrogen, (C1-C4)-alkyl or -CH2(CH2)mCOOCH2CN; R4 is -COCH3, -CO C2H5, -SO2CH3 or SO2C2H5; n and m are independently 0,1 or 2, with the proviso: -When, Y and Z both are Cl, R1 is other than methyl. When, R2 is Hydrogen and R3, R4 both are alkyl, R1 is selected from NHSO2CH3 or NHSO2C2H5. Disperse dyes of Formula (I) have excellent washing fastness and light fastness on polyester fiber and polyester blends.
