For many years, researchers have been attracted towards 1, 3-diaryl-2-propen-1- one(DPO) compounds. Generally, DPOs have been studied for their versatile biological activities. Heterocyclic compounds have been synthesized from DPOs and their biological activities have been explored in detail. DPOs have wonderful colours. Hence, they may be considered as colourants for various fabrics. For the present study, six DPOs were synthesized, and dyeing was carried out on synthetic fabrics like polyester and nylon. Extent of exhaustion of dye bath and extent of fixation on the fabrics were determined. Their light fastness and wash fastness properties were evaluated. Good colourant properties of DPOs were noticed for synthetic fabrics.
