Abstract
Preparation of fluorescent three inkjet inks based on N-(4-bromophenyl)-2-(2-imino-2H-chromen-3-yl) benzo[d]thiazole-5-sulfonamide derivatives the structures of compounds are confirmed via, element analysis, IR, H-NMR, and Mass spectra, microencapsulation and surface modification methods are used to prepare the inks, then printed on polyester, polyamide and paper, by inkjet printing technique as a printed security features. The prints posse very good fastness properties and high fluorescence emission
