This report deals with azodyes naturalised through glycoconjugation with a very common saccharide -lactose- and with its galactose and glucose components. The conjugation takes place through a bifunctional linker, here a terminal dibromoalkane, so the final products are very stable diether derivatives of the starting dyes. These transformations produce nat uralised dyes -indeed, water-soluble and multipurpose- that are able to dye different materials without addition of chemical additives such as surface agents
