Abstract
Disodium 4,4'-bis(1,3,5-triazin-6-yl)diaminostilbene-2,2'-disulfonate derivatives (9a-i) which were asymmetrically substituted with various nucleophilic substituents on triazine moiety were prepared. The obtained compounds were characterized by the analysis of the proton NMR spectrum and confirmed by UV spectrum. The physical properties of the derivatives were performed by fastness test and whiteness measurement. The chlorinated water fastness, rubbing fastness, and light fastness of newly synthesized compounds (9a-i) were investigated and compared with CI86. (C) 2004 Published by Elsevier Ltd.
