    Abstract: Dyeing and/or printing textile materials by treating them, if necessary at elevated temperature, in the presence of a strongly alkaline reacting agent with an uncoloured polyfunctional compound which has at least three ethylenimino groups preferably attached by way of carbon or to phosphorus, said ethylenimino groups if desired bearing one or more aliphatic radicals or which is capable of forming such groups during the process and with an azo dye or a precursor thereof which contains at least one -NH- group in heterocyclic combination and completing the formation of the azo dye on the fibre when a precursor is used. Metal complexes of the said azo dyes may be used or, when using azo dyes that are metallisable, the metallisation may be performed on the fibre. A number of suitable diazo and coupling components as well as azo dyestuffs are specified. In all other respects statements made in the parent Specification hold good. Examples are given.
