UV Protection and Photostabilization of Dyes Provided by Benzophenone UV Absorbers Containing a Built-in Benzotriazole Moiety

抄録

The textiles for protection against harmful UV radiation have become the focus of great interest in the present time, but all apparel is not well-protected against UV light ; application and improvement of UV absorbers for sun protective fabrics is therefore being sought. A number of different types of UV absorbing compounds were prepared as a means of development of UV protective fabrics. It was found that hydroxybenzophenones bearing groups which are capable of acting as benzotriazole UV absorbers show very high UPF, and play an important role in improving the light fastness of dyes. It was proposed that 2‚2’‚4‚4’-tetrahydroxy-5‚5’-dibenzotriazolylbenzophenone and its derivatives may be used as effective UV absorbers for sun protective fabrics.
