Zusammenfassung:	The invention concerns a vat dye that is covalently bonded to a polymeric moiety. The invention further concerns a process for making such a vat dye, and the use thereof in a composition for dying textiles or for printing, which can be used in particular for making marking or security features. According to a preferred embodiment, the polymeric moiety increases at least one of the solubility and the dispersibility of the vat dye in a polar solvent medium.
