Novel dyestuffs have been found which are obtainable by reacting A) polyamines containing at least 2 primary or secondary amino groups with B) reactive compounds containing at least two groups which are reactive towards primary and secondary amines in an amount of 5 to 95 mol %, relative to the primary and secondary amino groups of the polyamine, and C) dyestuffs containing at least one acylatable primary or secondary amino group in an amount of 10 to 200 mol %, relative to the reactive compound, and D) carbonyl- or sulphonyl-containing acylating agents in an amount of 5 to 95 mol %, relative to the primary and secondary amino groups of the polyamine and can be used in particular for coloring and printing cellulose-/amido-containing materials and as recording fluids for ink- jet recording systems. |
