Abstract

Dyestuffs of the formula ##STR1## wherein R represents C.sub.1 -C.sub.5 -alkyl which is optionally substituted by fluorine, chlorine, hydroxyl or methoxy, are outstandingly suitable for printing polymeric materials in accordance with the transfer printing principle in that they produce intensely colored prints on these materials, especially on polyester and polyamide fibre materials.
