The compounds of the formula <IMAGE> where the substituents and indices are as defined in claim 1, are green direct dyes for various substrates, in particular cellulosic fibre materials. They are high-temperature stable and therefore are particularly highly suitable for the one-bath, single-stage dyeing of polyester/cotton blend fabrics together with a disperse dye for the polyester fibres under the dyeing conditions for polyester fibres.
