Abstract
A series of crown ether based azo dyes (7a–10) were obtained by the coupling of crown ether based diazonium chloride with various substituted naphthols (3a–3f), pyrazolones (4a–4d), acetoacetanilides (5a–5d) and barbituric acid (6). The synthesized dyes were purified and characterized by elemental analysis, FT-IR, 1H NMR and FAB mass spectra. The absorption properties of the synthesized dyes were studied and their application in solvent based inks was investigated; the fastness properties of formulated inks were also studied.
