Naturalised dyes: A simple straightforward synthetic route to a new class of dyes - Glycoazodyes (GADs)

We report a process to naturalise synthetic azodyes through their linkage with lactose, or its monosaccharide components, either galactose or glucose, to enhance their solubility, as many other natural dyes. This modification allows the dyeing process of

Colouring agent containing a mono- or disaccharide

The present invention concerns new colouring agents comprising a chromophore bound to one or more molecules of a mono- or di-saccharide, the process to prepare them, and their use in the dyeing of textile fibres.
