Journal Textile Coloration and Finishing Year / Vol., Issue, Month 2021 / V.33,no.4,Dec Title A Study of Thermal-stability of Blue Dyes Depending on Dye Chromophore and Substituents Authors Tae Hyeon Kim, Ju Hong Lee, Eun Jin Kang, and Jae Hong Choi* Institution/Affiliations Kyungpook National University Pages/Total page pp.169 ~ 181 / 13 Language Korean 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.
