Reactive dyes, i.e. dyes which form covalent bonds with the substrates or which polymerise with themselves with the reactive group not directly attached to a heterocyclic ring the reactive group being an acryloyl group, a quaternised or non-quaternised aminoalkyl carbonyl group or a (—N)—CO—A—O—X or (—N)—CO—A—Hal group, wherein A is an alkylene or alkylidene group, X is hydrogen or an acyl radical of an organic or inorganic acid, Hal is a halogen atom, and n is 0 or 1
