Abstract
AbstractThree dyes–diesters of monoimides of perylene‐3,4,9,10‐tetracarboxylic acid were synthesized in three‐stage process: esterification, hydrolysis, and monoimidation as potential fluorescent light‐stable colorants for high visibility safety wear. The structure of these compounds was confirmed by 1H nuclear magnetic resonance spectroscopy and mass spectrometry, and their spectroscopic and physicochemical properties were determined. Colorants were applied to dyeing polyester fibre and polystyrene and poly (methyl methacrylate) films. The light, wash, and rubbing fastness of the dyeings were determined, and chromaticity coordinates were measured and discussed.
