Abstract

A stable, concentrated aqueous dye solution comprising a mixture of dyes of the formula I < IMAGE > is prepared by diazotising a crude amine mixture as obtained by sulphonating the distilled products of the reaction of an amine of the formula < IMAGE > or mixtures thereof, where Z is hydrogen or C1-C4-alkyl, with sulphur in the presence of sodium carbonate and which contains as the main ingredient an amine of the formula II < IMAGE > and reacting the diazonium salt in the presence of a tertiary amine with a compound of the formula III < IMAGE > in which formulae the symbols are each as defined in Claim 1. The dye solutions obtained are homogeneous and can be used in particular for dyeing paper material, the dyeings obtained being light-fast and having a greenish yellow hue.
