| Abstract: | New dyes – aliphatic esters of 1,6,7,12‐tetrachloroperylene‐3,4,9,10‐tetracarboxylic acid – were prepared as potential fluorescent light‐stable colorants for high‐visibility safety wear. The structure of the 15 perylenes was confirmed by 1H and 13C nuclear magnetic resonance spectroscopy and mass spectrometry, and their spectroscopic and physicochemical properties were determined. An attempt was made to apply the synthesised products as disperse dyes in the coloration of polyester as well as in the mass coloration of polystyrene and poly(methyl methacrylate). The light, wash, and rubbing fastness of the dyeings were determined, and chromaticity coordinates of selected samples were measured and discussed. |
