Abstract:
A method for preparing novel dibenzoylresorcinol-based compounds is disclosed, wherein the dibenzoylresorcinol is bonded to a substituted or unsubstituted aryl group which does not include a pendent hydroxyl group. The groups attached to the dibenzoylresorcinol may contain a wide variety of functional sites which permit further reaction, e.g., copolymerization. The described compounds are very useful as UV light absorbers and may be used to form improved coating compositions which usually include a transparent, polymeric matrix material. The coating compositions may be applied to various substrates, e.g., thermoplastics, to afford a selection of enhanced properties, such as UV light resistance and abrasion resistance.
