Abstract
Abstract The instant invention is directed to novel silylated agents having the formula <IMAGE> (II) where Ar and Ar' are independently substituted or unsubstituted aromatic rings, R is a branched or unbranched chain of 1 to 6 carbons, R' and R'' are independently C1 to C12 alkyl or mixtures of C1 to C12 alkyl, and n is 1 or 2. The novel dibenzoylresorcinol silylated agents are capable of absorbing ultraviolet light.
