Abstract

Isomer-free o-coupling products of 1-hydroxy-6-amino-3-sulphonaphthalene are obtained by coupling a diazotised or tetrazotised amine of the formula < IMAGE > wherein D denotes the radical of a diazo or tetrazo component and n denotes 1 or 2, with 1-hydroxy-6-amino-3,5-disulphonaphthalene and treating the resulting compound with acid. The products obtained may be used as dyes or may be reacted further, for example with phosgene to give I-acid urea dyes, or with fibre-reactive acyl compounds to give reactive dyes.
