Abstract
A 3-phenyl-3H-1-benzofuran-2-one compound is substituted with one or more acyloxy groups comprising 26 or more carbon atoms. A compound comprises two or more 3-phenyl-3H-1-benzofuran-2-one moieties and a second moiety selected from the group consisting of divalent and polyvalent C4-C60 hydrocarbon moieties. Each 3-phenyl-3H-1-benzofuran-2-one moiety is covalently bound to an open valence of the second moiety through a linking group selected from the group consisting of a carboxy group and oxyalkylene ester moieties. A composition comprises the 3-phenyl-3H-1-benzofuran-2-one compound described above or the compound described above comprising two or more 3-phenyl-3H-1-benzofuran-2-one moieties.
