A series of new quinazolinone based mono azo reactive dyes (D 1-10 ) have been prepared by subsequent diazotization of 2-phenyl-3-[4 0 -(4 00 -aminophenylsulphonamido)]phenyl-4(3H)-quinazolinone-6-sulphonic acid (C) and coupling with various 4-chloro anilino cyanurated coupling components. These dyes give purple, red, orange and yellow color shades. All the reactive dyes were characterized by their percentage yield, UV-Vis spectroscopy, elemental analysis, IR spectroscopy, 1 H NMR spectroscopy
