Abstract

The copper compound of the disazo dyestuff 6 - chloro - 2 - aminophenol - 4 - sulphonic acid \sQ 5 : 5<1> - dihydroxy - 2 : 2<1>-dinaphthylamine-7 : 7<1>-disulphonic acid is made by treating the dyestuff with copper or an agent yielding copper, e.g. copper sulphate. It dyes cotton in violet shades of excellent fastness to light. Specifications 1611/15 and 12932/15, [both in Class 2 (iii)], are referred to.
