Dyeings were carried out on polyester with benzodifuranones, naphthodifuranones and naphthofuranonepyrrolidones (which had been synthesised previously) to study dyeing properties. Symmetrically and asymmetrically substituted naphthodifuranones showed poor dyeing properties in terms of dyeing and fastness. Asymmetrically substituted red benzodifuranones showed excellent dyeing properties and fastness. Asymmetrically substituted blue benzodifuranones showed good dyeing properties; however, the colour hue was dull and the light fastness was inferior. The naphthofuranonepyrrolidones showed similar dyeing and fastness to those of symmetrically substituted naphthodifuranones, but the colour hue was duller.
