Cationic Dyes Derivatives of Compact Condensed System
2-Aminothiazolo <5,4-f> Indazole. Synthesis and Characterization

Abstract:

The synthesis and characterization of some new cationic dyes derivatives from heterocycle system with thiazolic ring, 2-aminothiazolo[5,4-f]indazole were described. These dyes were elucidated by chemical and spectral analyses, VIS, NMR and IR, confirming the structures propose. The results obtained by dyeing polyacrylic fibres (the intense and brightness color, fastness to washing, fastness to perspiration, fastness to friction, exposure to sunlight, ability to be absorbed) and the relationship between chemical structure of some cationic dyes and perspiration/light fastness were discussed. Keywords: 2-aminothiazolo[5,4-f]indazole, dimethyl sulfate, cationic dye, polyacrylic fibre
