摘要：

The synthesis of five new reactive triazine azodyes and their intermediates was investigated. Three of these dyes contained a tetramethylpiperidine (TMP) fragment and four of them contained a polymerizable group in their molecule. Two different reaction schemes for synthesis were studied and the most suitable one was found. The quantitative thin-layer chromatography (T1c) to monitor the synthesis was applied. Cotton fabrics were dyed and their color characteristics were measured. The dyes copolymerized with acrylamide (ACA) and acrylonitrile (AN) and the copolymers with an intense orange color that is stable to solvent extraction were obtained. The photostability of the dyes in solution and on cotton fabrics was studied and it was found that two of the dyes, containing a TMP fragment, had good photostability and can be recommended.
