应用领域
用途1
直接铜盐灰 GRL 适用于棉、黏胶纤维及其混纺织物的染色，也用于棉、黏胶纤维织物的直接印花或地色拔染印花。移染性差，匀染性好，上染率尚好。除单独使用外，也可与绿色、棕色染料拼色。通常染色后用硫酸铜或铜盐固色剂处理。
制备方法
方法1
以 4-硝基邻甲氧基苯胺、5-硝基邻氨基苯甲酸、H 酸、5-氨基水杨酸和 J 酸为原料，首先将 5-硝基邻氨基苯甲酸重氮化，与 H 酸偶合后，再将 4-硝基邻甲氧基苯胺重氮化，与第一次偶合产物第二次偶合，然后将两个硝基还原，并进行双重氮化。另外，先将 5-氨基水杨酸重氮化，再与 J 酸偶合，最后将此偶合产物与前述双重氮化产物进行偶合得最终产物。经盐析、过滤、干燥、粉碎得成品。。。
