Abstract

NINE novel azo dyes containing UV absorber (anti-UV dyes) ……were synthesized by diazotization of primary aromatic amines (p.NO2, p.Cl, p.Br aniline) and then coupling with J- acid coupler. The resultant intermediates were also diazotized and coupled with anti-UV functional finishing groups (resorcinol, 2, 4- dihydroxy benzophenone, 1- hydroxy benzotriazol sulfonic acid UV absorbers). The structure of the synthesized dyes was fully elucidated using FTIR and 1H-NMR. All synthesized dyes were applied on nylon fabrics. Fabrics dyed with anti-UV dyes were tested for color strength (K/S), rate of fading (ΔE) values and fastness properties.
