AB  - A series of novel anchored mono‐ and disarylazo cationic pigments embodying long chain aliphatic amine moiety, as deflocculating unit, were prepared by amination of the newly synthesized heterocyclic Hansa Yellow analogue derivatives IVa‐g followed by reacting the products with p‐nitroso‐N,N‐dimethyl aniline. Synthesis and spectral behaviour of these products as well as their precursors were fully investigated. The hitherto prepared organic colourants showed preliminary improved bleeding and fastness properties.
