    • PURPOSE: A disperse dye is provided to have remarkably excellent initial dyeability when dyeing polylactic acid fibers, and to have excellent color shade and fastness. CONSTITUTION: A blue disperse dye compound has a structure represented by chemical formula 1, a red disperse dye compound has a structure represented by chemical formula 2, and a yellow disperse dye compound has a structure represented by chemical formula 3. In chemical formula 1, R1 is -NO2 or -COOCH2H3; R2 is -H, -CH3, or -NH-CO-CH3; R3 is -H or -OCH3; R4 is -CH2CH2-O-COCH3 or -CH2CH2-O-CH2CH2OH; and R5 is -CH2CH3, -CH2CH2-O-COCH3, or -CH2CH2-O-CH2CH2OH. In chemical formula 2, R1 is -CH3 or -NH-CO-CH3; R2 is -H or -OCH3; each of R3 and R4 is -CH2CH=CH2, -CH2CH3, or -CH2CH2-O-COCH3.
    • 目的:提供分散染料,以在染色聚乳酸纤维时具有显着优异的初始染色性,并且具有优异的色调和牢度。 构成:蓝色分散染料化合物具有由化学式1表示的结构,红色分散染料化合物具有由化学式2表示的结构,黄色分散染料化合物具有由化学式3表示的结构。在化学式1中, R1是-NO2或-COOCH2H3; R2是-H,-CH3或-NH-CO-CH3; R3是-H或-OCH3; R4是-CH2CH2-O-COCH3或-CH2CH2-O-CH2CH2OH; 和R 5是-CH 2 CH 3,-CH 2 CH 2 -O-COCH 3或-CH 2 CH 2 -O-CH 2 CH 2 OH。 在化学式2中,R 1是-CH 3或-NH-CO-CH 3; R2是-H或-OCH3; R 3和R 4各自为-CH 2 CH = CH 2,-CH 2 CH 3或-CH 2 CH 2 -O-COCH 3。
