Abstract: Thin walled products having good scratch resistance are disclosed, as are processes for making such products (e.g. films, sheets, and thin walled articles). The product includes a thin layer formed from (A) a cross-linkable polycarbonate resin having endcaps derived from a monohydroxybenzophenone; and (B) if desired, a base polymeric resin. When exposed to ultraviolet light, crosslinking will occur in the layer with the cross-linkable polycarbonate resin, enhancing the scratch resistance properties of the thin layer and the overall product.
