    • PURPOSE: A yellow azo disperse dye is provided to obtain the same concentration of color even from a small amount of dye when dying because of excellent lightproof, inside sublimability, dispersability, and a high molar extinction coefficient, is also environmentally friendly, and reduces the production costs. CONSTITUTION: A yellow azo disperse dye is indicated as chemical formula 1. In the chemical formula 1, A is selected from the compounds from the chemical formula 1-a. R1-R3 are respectively selected from hydrogen, hydroxyl group, amide group, nitro group, acetyl group, C1-6 alkyl group, C1-6 haloalkyl group, C1-6 alkoxy group, C6-14 aryl group and SO2R7. R4-R6 is respectively selected from hydrogen, C1-6 alkyl group, C1-6 halo alkyl group, C1-6 alkoxy group, nitro group or halogen group. R7 is selected from C1-6 alkyl group, C1-6 alkylamine group, and C6-14 arylamine group or C1-6 acetoxyalkyl group.
    • 目的:提供黄色偶氮分散染料,即使由于优异的耐光性,内部升华性,分散性和高摩尔消光系数而在染色时由少量的染料得到相同的颜色浓度也是环保的,并且减少了 生产成本。 构成:黄色偶氮分散染料用化学式1表示。在化学式1中,A选自化学式1-a的化合物。 R1-R3分别选自氢,羟基,酰胺基,硝基,乙酰基,C 1-6烷基,C 1-6卤代烷基,C 1-6烷氧基,C 6-14芳基和SO 2 R 7。 R4-R6分别选自氢,C1-6烷基,C1-6卤代烷基,C1-6烷氧基,硝基或卤素基。 R 7选自C 1-6烷基,C 1-6烷基胺基和C 6-14芳基胺基或C 1-6乙酰氧基烷基。
