Abstract
A novel molding composition is described which prevents plateout of pigment on the surface of a mold or shaping apparatus during the molding or shaping operation. The composition has improved thermal and oxidation stability as well as increased compatibility of the components of the composition. The composition comprises a thermoplastic resin, a fluorescent pigment, a metal salt or complex, polymer or oligomer reagent containing a reactive functionality and other conventional additives. The composition is useful in preparing such molded articles as films, bottles, closures, furniture and toys.
