Abstract: The invention relates to a thermoplastic composition used for forming articles having both high gloss and excellent resistance to mar, scratch and/or abrasion. The composition contains very high levels of nano-sized inorganic additives, such as alumina, silica and titanium dioxide. Acrylic polymer compositions, such as Arkema's PLEXIGLAS® resins, with 5 to 25 weight percent of sized fumed silica are a preferred embodiment of the invention, especially when combined with a dye or pigment.
