Disperse Dyes Based on 2 -N , N- Dibutylamino-4-phenyl thiazole: Synthesis, Solvatochromism, and Dyeing Studies
Source abstract
Abstract
The coupler 2- N, N-dibutylamino-4-phenyl thiazole was used in the preparation of five novel monoazo disperse dyes. Effects of substituents on the electronic absorption properties of the dyes were studied by UV-Vis spectroscopy. The resulting dyes showed little positive solvatochromism, whereas a bathochromic shift in absorption maxima was observed for all five dyes in highly polar solvents. These dyes showed good discharge ability on polyester fabric when compared to nylon fabric and their fastness properties were evaluated. Being low melting, the new dyes could be used for heat transfer printing at a particular set temperature.
