Resumo: A series of monoazo dyes was prepared by coupling carbocyclic and heterocyclic diazo components to four compounds of the N, N-dialkylaniline type. The dyes were characterised by spectroscopic methods, elemental analysis or mass spectrometry. Dispersions of the dyes were applied by conventional techniques to polyester and polyamide, or by reactive dyeing to wool and polyamide, when a CO2H group was present. Wash and light fastness ratings of coloured samples are presented.

Os corantes foram caracterizados por métodos espectroscópicos, análise elementar ou espectrometria de massa. Foram aplicadas dispersões dos corantes a poliéster e poliamida, ou por tingimento reactivo à lã e poliamida, quando o grupo CO2H estava presente. Apresentam-se os resultados da resistência à luz e à lavagem das amostras coradas.University of LeedsUniversidade do MinhoMiranda, Paula C.Rodrigues, Lígia M.Gonçalves, M. Sameiro T.Costa, Susana P.
