Abstract |
Five dyes based on phthalocyanine, a dye on azo, and a dye on anhraquinone
were prepared from corresponding starting material to investigate the effects of
substituent on thermal-stability of dyes which is essentially required to apply to the
color filters. Synthesized dyes were confirmed their chemical structure using by
1H-NMR, MASS and Elemental analysis. The thermal-stability was evaluated by the
weight reductions measured by TGA analysis comparing to that of conventional C.I.
Pigment Blue 15:6. The absorption maxima were measured by UV-VIS spectrophotometer
then the effects of substituent on absorption maximum was also investigated. |
