Abstract

Tetrazotized (4 . 4<1> - diaminodiphenylene - 3 . 3<1>) - bis - glycollic acid is coupled with 2 - amino - 5 - naphthol - 7 - sulphonic acid or its halogen, N-alkyl, or N-aryl substitution products and the dyestuffs so obtained treated on the fibre with an agent yielding copper to give blue shades fast to washing, light, and acids. In examples, the tetrazotized body is coupled with 2-p-anisidylamino-5-naphthol-7-sulphonic acid or with the corresponding 2-phenyl, 2-m-carboxyphenyl, 4<1>-hydroxy-3<1>-carboxy - phenyl - 2 - amino, 2 - (3<1> - sulpho - 4<1> - amino - diphenylyl - 4 - amino), 2 - diethylamino, 2 - dimethylamino, 2 - methylamino, 2-ethylamino, or 1-chloro-2-amino naphthol sulphonic acids. Specification 14620/90, [Class 2], is referred to.
