Abstract: A BS T R A C TIn a four-step synthesis, a series of N-arylideneamino p-substituted pyridinium salt derivatives were prepared for use as cationic azomethine disperse dyes for polyester andpolyacrylonitrile fibres. The efect of diferent substituents, in both of homo-and heterocyclic ring systems, on position of maximum absorbance in UV-vis spectra was used to explain the dgerent hues of the prepared dyes. Besides, showing promising tinctorial properties, the synthesised dyes revealed fungicidal activity against…
