Azo Disperse Dyes for Synthetic-Fibers .1. 2-Methylquinazolone and 2-Phenylquinazolone Derivatives
Ten variously substituted derivatives (IVa-j) of 4’(quinazol-4-on-3-yl) azobenzene were prepared. The effects of the nature and orientation of the substituents on the colour and dyeing properties of these dyes on polyester and acrylic fibres were evaluated.
