Abstract

Disazo dyes of the formula I where the symbols have the meanings indicated in Claim 1 are obtained by coupling delta -acid onto the corresponding, diazotised monoazoamine. The latter can be obtained from the components, likewise by coupling. The dyes are suitable in particular for dyeing polyamide and leather in blue or violet shades. <IMAGE>
