Abstract:
1. A process comprising coating an acrylic polymer onto a polyvinyl fluoride (PVF) cast film or a polyvinylidene fluoride (PVDF) cast film to produce a coated film; extruding a metallocene catalyzed very low density polyethylene (m-VLDPE) polymer layer onto the surface of the coated film to produce a sheet; optionally attaching the PVF film or the PVDF film to a supporting film of a biaxially oriented polyester film to produce a structure; passing the sheet or the structure into a nip of two rolls under pressure; subsequently, optionally extruding or laminating a third polymer layer onto the m-VLDPE polymer layer; wherein the acrylic polymer comprises one or more UV absorbers, UV stabilizers, or mixtures thereof; the m-VLDPE polymer layer contains pigments, flakes, dyes, or flake pigment, and optionally other additives; and the sheet has a distinctness of image of at least 60.
