Antioxidants are of special interest because they are probably the most effective light stabilizers (Crews and Clark, 1990). Antioxidants are organic compounds that are added to oxidizable organic materials to retard autooxidation and, in general, to prolong the useful life of the substrates. Relatively few chemical classes are effective as antioxidants. Those in common use today are hindered
