以1-氨基蒽醌和1-苯基-3-甲基-5-吡唑啉酮为原料，通过重氮化偶联反应合成了在聚乳酸纤维上具有高耐光牢度的1-苯基-3-甲基-5-吡唑啉酮偶氮蒽醌染料。这些新染料的结构通过质谱、红外和质子核磁共振光谱以及燃烧分析得到证实。同时测定了它们在聚乳酸纤维上的染色性能，结果表明，标题染料可在较低的染色温度下使用，且相应的染色织物具有良好的牢度性能。
1-Phenyl-3-methyl-5-pyrazolonyl azo-anthraquinone dyes having high light fastness on polylactide fibres were synthesised from 1-aminoanthraquinone via a diazotisation-coupling reaction with 1-phenyl-3-methyl-5-pyrazolones. The structures of these new dyes were confirmed using mass spectrometry, infrared and proton nuclear magnetic resonance spectroscopy and combustion analyses. Their dyeing behaviour on polylactide fibres was also determined, whereupon it was found that the title dyes could be applied at a relatively low dyeing temperature and that the corresponding dyed fabrics had good fastness properties.
