    • 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.
    • 本发明涉及式(1)的分散染料,其中X,Y和Z独立地为氢,卤素,氰基,硝基或SO2F; 其中X,Y和Z中的至少一个为SO 2 F。 R1是氢,甲基,羟基或NHR4; R2是氢,氯或甲氧基; R3是氢,(C1-C4) - 烷基或-CH2(CH2)nCOOCH2CN; R5是氢,(C1-C4) - 烷基或-CH2(CH2)mCOOCH2CN; R4是-COCH3,-CO C2H5,-SO2CH3或SO2C2H5; n和m独立地为0,1或2,条件是:当Y和Z均为Cl时,R 1不是甲基。 当R2为氢,R3,R4均为烷基时,R1选自NHSO2CH3或NHSO2C2H5。 式(I)的分散染料在聚酯纤维和聚酯共混物上具有优异的耐洗牢度和耐光性。
