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.

摘要:
A monoazo dye for polyester fiber represented by formula ##STR1## and having a crystal modification characterized by an X-ray diffraction spectrum (CuK.alpha.) showing a very strong peak at an angle of diffraction (2.theta.) of about 14.2.degree., a strong peak at about 24.5.degree., and four weak peaks at about 16.9.degree., 23.6.degree., 25.3.degree., and 26.8.degree.. The monoazo dye exhibits excellent dispersibility to effect level dyeing even under high temperature and severe conditions and provides a dyed material excellent in light fastness and rubbing fastness, as well as wet fastness after post-finish.
