| Research Abstract |
Numerous potential UV absorbers containing a singlet oxygen quenching moiety were prepared as a means of application and improvement of UV absorbers for sun protective fabrics. Their ultraviolet-visible absorption spectra and inhibiting effect on the fading of dyes was examined in polymer substrate. It has been found that these compounds effectively absorb the harmful UV light and were very effective in reducing the fading.
Various kinds of benzophenone UV absorbers bearing benzotriazolyl groups were further synthesized in an attempt to increase the Ultraviolet Protection Factors (UPF) of UV absorbers, and improve the light fastness of dyes. It was found that new compounds show very high UPF, and play an important role in improving the light fastness of dyes.
