Summary

Substituted benzotriazoles were synthesised from 4-amino-3-nitro benzophenone and couplers such as β-Naphthol (BN), p-Cresol (PC) and 2,6-xylenol (XY). The reactions were monitored by thin layer chromatography (TLC). The products were characterised by melting point, ultraviolet (UV) and infrared (IR) spectra. Stabilising action of prepared 2-(5-Benzoyl-2H-benzotriazol-2yl)-4methyl phenol, 2-(5-Benzoyl-2H-benzotriazol-2yl)-4,6-dimethyl phenol and 2-(5-Benzoyl-2H-benzotriazol-2yl)-naphthol for protecting paint against photo-oxidation was examined by a QUV weatherometer. The effect of exposure on the properties of paints such as gloss, whiteness and yellowness was evaluated. Results show that paints containing prepared UV absorbers (UVA) possessed better stabilising effects against photo-oxidation than those employed on standard paints available in the market.
