A composition includes specific amounts of a poly(alkylene terephthalate) and an epoxy compound having a weight average molecular weight of at least (500) daltons, and an epoxy equivalent weight of at least (400) grams per equivalent. The composition exhibits high melt flow, and articles molded from the composition exhibit reduced high-temperature outgassing compared to corresponding compounds without the epoxy compound. The composition is suitable for molding directly metallizable reflectors and bezels for automotive headlights.
