The synthesis, properties and application of some 1,8-naphthalimide dyes

The synthesis of two, unsaturated 1,8-naphthalimide derivatives was studied; it was found that the synthesis of the two dyes was more efficient than previously reported. Quantitative thin-layer chromatography (tlc) was used to monitor the process and check the purity of the products. The dyes were copolymerized with methylmethacrylate (MMA) giving polymers with intense colour and fluorescence that were stable to solvent extraction. Wool and polyamide fibres were dyed and the colorimetric characteristics of the dyed fabrics were measured.
