Beschreibung
Zusammenfassung:	A compound is claimed of formula (I); Ar1, Ar2 = optionally substituted monocyclic or polycyclic aryl; R = H, aryl or 1 - 10C alkyl; A = (a) a radical derived from an alcohol or carboxylic acid, or (b) an optionally substituted aryl not including a pendant hydroxyl. Also claimed are (1) Preparation of a derivative of a dibenzoylresorcinol compound, comprising: (a) reacting a mixture of a 4,6-dibenzoylresorcinol and a para-aldehyde with a secondary amine catalyst and a carboxylic acid solvent under reactive conditions to form a methylene carboxylate intermediate in which the methylene bridge forms a linkage between the dibenzoylresorcinol residue and a carboxylate moiety; and (b) reacting the methylene carboxylate compound with an alcohol or carboxylic acid in a reactive medium to form the derivative; (2) A coating composition comprising: (i) an ultraviolet (UV) light-absorbing compound of formula (I); and (ii) a substantially transparent matrix composition. (3) A solid substrate with coating composition (2) applied thereon.
