    Abstract: The invention concerns reactive dyes of formula (I) in which: a designates 1 or 2; b designates 0 or 1; Y stands for vinyl or a radical of formula C2H4Q, in which Q stands for a group which can be separated in alkaline reaction conditions; Het is the radical of a 5- or 6-member aromatic heterocyclic ring, which comprises between 1 and 3 heteroatoms, selected from the group comprising oxygen, sulphur and nitrogen; W, in the first instance, is the radical of a coupling component, a monoazo dye or additionally, if b = 0, of a disazo dye which can carry further fibre-reactive groups, or, in the second instance, the radical of a chromophore which optionally comprises other fibre-reactive groups and is derived from an optionally metallized mono- or disazo dye, a triphene dioxazine, an anthraquinone, a metallized formazan or a metallized phthalocyanine; and L and L each designate a bridge member. The invention further concerns a process for dyeing or printing substrates comprising hydroxy groups or nitrogen atoms using the novel dyes.
