Abstract

Three novel trisazo, monochloro-s-triazinyl (MCT) reactive dyes were synthesised with a view to achieving heavy bright shades on cotton by exhaust dyeing using low concentrations of salt. Unfortunately, the dyes proved to be dull violet in shade, exhibiting modest build-up and poor level of dyeing and wash fastness properties, although two of them exhibited their optimum colour yield using low salt quantities (0–30 g/l).
