Abstract

Azo dyes of the formula I having the symbols as defined in Claim 1 are obtained by diazotising and coupling from a diazo component of the formula II and a coupling component of the formula III the symbols are defined in Claim 1. When Q is H, a reaction with a carbamic acid derivative of the formula O=C=N-Z or Hal-CO-NH-Z is carried out subsequently, and when Q is phenoxycarbonyl, the subsequent reaction is with an amine Z-NH2. The dyes obtained can be used for colouring synthetic hydrophobic fibres with good fastness properties.
