Abstract

1-Aralkylamino- or 1-dialkylamino-4-p1-oxyaryl-naphthylamine sulphonic acids are obtained by treating with sulphites the indophenols derived from 1-aralkyl- or 1-dialkyl-naphthylamines and p-aminophenols; in examples, the indophenols from benzyl-a -naphthylamine and quinone chlorimide, or dimethyl-a -naphthylamine and p-aminophenol, are treated with sodium bisulphite. Sulphuretted dyes, dyeing cotton green shades fast to soap, are obtained by heating the above-described sulphonic acids, or their alkali salts, with alkali polysulphides in the presence of copper.
