Patent

CA 1328553

ABSTRACT Extruded multilayer synthetic resin sheets are prepared wherein at least one coextruded removable layer is employed to maintain the concentration of exudable additive(s) (e.g., UV absorbant) at the sheet surface (after removal of said protective layer) and protect the production equipment from exuded amounts of such additives. A further advantage of the present invention is the avoidance of a secondary lamination step wherein such a protective layer would be provided solely for the purpose of protecting the sheet surface during handling, shipping, and installation.
