    • The present invention is directed to a disperse dye of formula (1) Wherein, X, Y and Z are, independently, hydrogen, halogen, cyano, nitro or SO 2 F; Wherein at least one of X, Y and Z is SO 2 F. R 1 is hydrogen, methyl, hydroxyl or NHR 4 ; R 2 is hydrogen, chloro or methoxy; R 3 is hydrogen, (C 1 -C 4 )-alkyl or -CH 2 (CH 2 ) n COOCH 2 CN; R 5 is hydrogen, (C 1 -C 4 )-alkyl or -CH 2 (CH 2 ) m COOCH 2 CN; R 4 is -COCH 3 ,-CO C 2 H 5 , -SO 2 CH 3 or SO 2 C 2 H 5 ; n and m are independently 0,1 or 2. with the proviso: - When, Y and Z both are Cl, R 1 is other than methyl. - When, R 2 is Hydrogen and R 3 , R 4 both are alkyl, R 1 is selected from NHSO 2 CH 3 or NHSO 2 C 2 H 5 . 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SO 2, F; 其中X,Y和Z中的至少一个是SO 2 F。 R 1为氢,甲基,羟基或NHR 4; R 2是氢,氯或甲氧基; R 3是氢,(C 1 -C 4) - 烷基或-CH 2(CH 2 )<子>名词 COOCH <子> 2 CN; R 5是氢,(C 1 -C 4)烷基或-CH 2(CH 2 )<子>米 COOCH <子> 2 CN; R 4是-COCH 3 3,-CO C 2 H 5,-SO 2 2, sub> CH 3 或SO 2 2 5 5 n和m独立地为0,1或2.附带条件是:当Y和Z均为Cl时,R 1不是甲基。 当R 2是氢和R 3时,R 4都是烷基,R 1选自 NHSO 2 CH 3或NHSO 2 C 2 H 5。5。 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。
