用途
- 化学性质
黑色粉末。水溶性一般，其水溶液呈紫黑色，加浓盐酸产生深棕色沉淀，加浓碱产生灰紫色沉淀。溶于乙醇呈灰光紫色。于浓硫酸中呈深蓝光绿色，稀释后产生紫棕色沉淀。
- 直接灰 D 广泛用于棉、黏胶纤维织物的染色，也用于蚕丝织物的染色和印花，得青红光灰至绿光黑色，色泽深浓，匀净。还可与黄、红、蓝、棕等染料拼色。染色后常用固色剂 Y 或固色剂 M 处理以及进行脲醛树脂整理。还可用于维纶织物染色。
- 主要用于棉、麻、粘胶等纤维素纤维织物的染色，也可用于蚕丝、锦纶及其混纺织物的染色，还可作粘胶及蚕丝织物的印花用。本品染棉、粘胶织物后，通常采用固色剂Y或固色剂M处理，以及进行脲醛树脂整理。经固色剂Y处理，色光呈微红；经固色剂M处理，色光转暗，经脲醛树脂整理，色光基本不变。
- 主要用于棉、麻、粘胶等织物的染色

用途
- 化学性质
棕色粉末。水溶性好，微溶于乙二醇乙醚、乙醇，不溶于其他有机溶剂。其水溶液呈品红色，加入浓盐酸产生紫色沉淀，加烧碱产生红色沉淀。于浓硫酸中呈灰光蓝色，稀释后呈紫色；于浓硝酸中部分溶解呈黑色。染色时遇铜、铁离子色光稍有变化。
- 直接耐晒桃红 BK 用于棉、黏胶纤维织物的染色和直接印花，得粉红色。具有良好的匀染性和移染性，上染率一般。染色后常用固色剂 Y 处理，以提高湿牢度，但色光稍蓝。也用于蚕丝、羊毛、锦纶织物的染色和印花以及与分散染料同浴高温染涤黏混纺织物。
