Previous work in this series has shown that Chlorantine Fast Violet 4BLN is a copper-complex of the azo-dye derived from 2-aminophenol-4-sulphonamide and di-J-acid. In this paper the authors have studied the constitution of Chlorantine Fast Violet 5BLL, which is a copper-containing direct azo-dye like the 4BLN.　The commercial dye was purified and then its Na- and Cu-contents were determined. The purified dye was reduced with stannous chloride and conc. hydrochloric acid, and from the reduction products 2-amino-phenol-4-sulphonamide and 6,6'-diamino-di-J-acid were isolated.　From the above results, it is concluded that Chlorantine Fast Violet 5BLL is a copper-complex of the 0,0'-dihydroxyazo-dye obtained by coupling diazotized 2-aminophenol-4-sulphonamide with di-J-acid.　In addition, Chlorantine Fast Violet 5BL and 5BLN were studied, and the same experimental results were obtained. Therefore, these constitutions also are identical with that of Chlorantine Fast Violet 5BLL.
