The textiles for protection against harmful UV radiation has 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. Various kinds of UV absorbers were synthesized in an attempt to increase the Ultraviolet Protection Factors （UPF） of UV absorbers, and prolong the life of dyes. It was found that hydroxybenzophenone bearing group which is capable of acting as benzotriazole UV absorber shows very high UPF value, and play an important role also in improving the light fastness of dyes. It was proposed that 2,2',4,4'-teterahydroxy-5-benzotriazolylbenzophenone may be used as effective UV absorber for sun protective sports wears.
