Six new azo disperse dyes were prepared from 4-phenoxyaniline through diazo coupling reactions. The structures of the azo dyes were identified by Fourier transform infrared, proton and carbon -13 nuclear magnetic resonance. All the compounds were tested for their fastness properties on nylon and polyester fabrics using pressure dyeing method. Results showed that the dyes gave brown colours on the two fabrics. The light fastness on nylon was 5 and 6 better than that of polyester. The sublimation fastness were between 3 and 4. The results of the fastness properties of the dyes indicate that they could be promising dyestuffs in the area of heat transfer printing of modern fibers.
