Abstract
A light stabilizer package is disclosed. The light stabilizer package comprises a monomeric HALS having a pKa of no greater than 7, an ultraviolet light absorber and, optionally, a polymeric HALS having a pKa of less than 7. The light stabilizer package may be blended with a thermoplastic olefin to form a moldable light stable composition. An article comprising the moldable light stable composition may have an exterior surface that is at least partially coated.
