Abstract

The synthesis of 6-nitro substituted 3-aryl-2-methyl-4(3H)-quinazolinones from readily available starting materials, such as isatoic anhydride, is described. One of these, 3-phenyl-2-methyl-4(3H)-quinazolinone, has been utilised to prepare a range of styryl disperse dyes for polyester. Novel azo disperse dyes based on 6-nitro-3-(m-diethylaminophenyl)-2-methyl-4(3H)-quinazolinone as coupling component are reported. The application properties of the dyes on polyester and their fastness properties have been evaluated, with the latter being disappointing.
