Abstract

The invention comprises the water-insoluble monoazo dyes of formula <FORM:1019782/C4-C5/1> wherein R is a hydrogen atom or an acetyl group. The dyes are prepared by coupling diazotized 2 - hydroxy- or -acetoxy - 4 - nitroaniline with N,N-di-hydroxy- or -acetoxy-ethyl-meta-toluidine and subsequently acetylating the monoazo dye if desired. The dyes give red shades on acetylcellulose, polyamide and in particular, polyester fibres from aqueous dispersions.
