A coating composition is disclosed. The coating composition includes a poly(methyl methacrylate) polymer or copolymer having a weight average molecular weight of at least 50,000 grams per mole; monomer comprising at least one of an alkylene diacrylate, alkylene dimethacrylate, cycloalkylene diacrylate, or cycloalkylenedimethacrylate, wherein the at least one of an alkylene diacrylate, alkylene dimethacrylate, cycloalkylene diacrylate, or cycloalkylenedimethacrylate provides at least 80 percent by weight of the monomer; and a stabilizer against ultraviolet light. An article including a coating on a surface of a substrate and a method of making the article are also disclosed. The coating on the surface of the substrate is obtained by curing the disclosed coating composition.
