In this study the synthesis of novel azo dyes containing selenium was designed and synthesized with high yields from simple aniline selenocyanate 1 which coupled with some diazotized aromatic amines to give new azo dye. The novel synthesized selenium dyes were utilized for silk screen printed polyester fabrics. Color strength and fastness properties were measured and exhibited high efficiency for washing, perspiration, rubbing, and light fastness. Moreover, the new dyes were tested for antibacterial activity.
