以含羧基的酸性染料为原料，经氯化、酰胺化反应合成了一系列含酰胺基的苯基偶氮吡唑啉酮分散染料。这些新染料的结构经傅立叶变换红外光谱、核磁共振氢谱、质谱和元素分析确证。研究了它们在不同溶剂中的溶致变色性质，发现酰胺染料溶于二甲基甲酰胺时，其吸收光谱较溶于丙酮时发生红移。它们的染色行为，包括染料的吸附，颜色建立和色牢度性能的聚（乳酸）纤维，也被确定，因此，它被发现，叔酰胺染料同时表现出高的染料吸附和令人满意的颜色建立和色牢度性能的聚（乳酸）织物。
A series of phenylazopyrazolone disperse dyes containing an acylamide moiety were synthesised from carboxyl-containing acid dyes via chlorination and amidation with different sorts of amines. The structures of these new dyes were confirmed by Fourier Transforminfrared, proton nuclear magnetic resonance, mass spectroscopy and elemental analysis. Their solvatochromic properties in different solvents were also investigated and the absorbance spectra of the acylamide dyes in solution exhibited a red shift when dissolved in dimethylformamide, compared with acetone. Their dyeing behaviour, including dye sorption, colour build-up and colour fastness properties on poly(lactic acid) fibres, was also determined, whereupon it was found that the tertiary acylamide dyes simultaneously exhibited high dye sorption and satisfactory colour build-up and fastness properties on the poly(lactic acid) fabric.
