    摘要: A process for dyeing acid-modified polyester fibers comprising contacting the fibers with a dye bath containing a thiazoleazotype cationic dye of the formula (I);

    wherein R1 and R3 are each a C1 - C2 alkyl group, R2 is a hydrogen atom, a C1 - C2 alkyl group or a C1 - C2 alkoxy group, R4 is a hydrogen atom or a C1 - C2 alkyl group, R5 is a hydroxyl group or a C1 - C2 alkoxy group, and X is an anion. The dye compounds of the formula (I) dye acid-modified polyester fibers a bright shade and with good light fastness. The dye compounds of the Formula (I) wherein R2 is a hydrogen atom or a methoxy or ethoxy group are novel dye compounds.
