After the diazotization ,2-aminophenol-4-(2-'carboxy)sulfanil phenylamine was coupled with acetoacetanilide,2-naphthol,1-phenyl-3-methyl-5-pyrazolone,1-naphthol-4-sulfonic acid,separately to get the different diazotized compounds,then complexed with potassium chromium sulfate or cobaltous chloride to obtain the yellow,orange,red,purple,blue and other colour dyestuffs.

2-氨基苯酚-4-(2'-羧基)磺酰苯胺重氮化，分别与乙酰乙酰苯胺、2—萘酚、1-苯基-3-甲基-5-吡唑啉酮、尼文酸、1-乙酰氨基-7-萘酚等偶合，得到不同的偶氮化合物，然后分别与硫酸铬或氯化钴进行络合反应，得到黄、橙、红、紫、蓝多种颜色染料，并进行了毛织品的染色实验。
