• 【用途一】
  用于纸张及棉丝织物的染色
  【用途二】
  直接黄 R 可用于棉、黏胶纤维及其针织品染色，得鲜艳红光黄色。匀染性和移染性均较差。染色后需经固色剂处理，以提高湿牢度。较多用于黏胶纤维与蚕丝交织物染色。也可用于蚕丝、羊毛的染色。本品具有较强的光脆损作用。
  【用途三】
  染棉或粘胶为鲜艳的红光黄色。匀染性和移染性差。染色后期自然降温到600C，以利染料吸尽。一般不用于印花。染色时应避免与铜、铁接触。大多用于棉针织物及绒毯、绒布等染色，很少染棉布，还适用于粘胶丝和蚕丝交织物的染色。

制备

【方法一】
以 5-硝基邻甲苯磺酸为原料，将其在氢氧化钠水溶液中加热，即发生自缩合反应得产物。由于氢氧化钠浓度、反应温度、反应时间不同，可得各种不同的黄色染料或染料混合物。
