The Application describes disperse dyes soluble in water of general formula (I)
D-L-Sn (I)
wherein:
D is a disperse dye insoluble in water
L is a linker
S is a sugar
n is comprised between 2 and 4
that are able to dye in an homogeneous way natural fibres and textiles and also textile materials including different fibres, and have high biodegradability through digestion by micro organisms, that found in the molecule itself a useful nourishment for their survival and proliferation; processes for the preparation of the above said dyes and their use are also described.

Recently we started to develop a new class of dyes based upon the glycoconjugation of disperse dyes with mono- or disaccharides. We used the term “naturalised” to describe these dyes because we used natural lactose in the glycoconjugation process, and also because they are similar to real natural dyes, the hydrosolubility of which is based upon the saccharidic moiety attached to the chromophore, as
