Two new zinc complexes were prepared from two different azodyes. They were characterized by various physico chemical methods. The dyes and their Zn(II) complexes were subjected to the dyeing property studies by dyeing on cotton fabrics. Colour fastness, fastness to light, perspiration, and sublimation fastness were analysed. The results show that the present dyes and their Zn(II) complexes have good affinity towards the fabric.
