Patent ID: 7303793

Claim:
A thermoformable multi-layer sheet comprising or produced from a cast film comprising a weatherable film and a second polymer layer wherein the weatherable film is a material selected from the group consisting of polyvinyl fluoride (PVF) and polyvinylidene fluoride (PVDF) and has an adhesive coating on one side of the cast film and the coating is an acrylic polymer comprising one or more UV absorbers, UV stabilizers, or mixtures thereof; the second polymer layer, extruded onto the adhesive coating of the cast film and the second polymer layer, is an ionomer resin of a copolymer of ethylene and 8-25% by weight, based on the weight of the copolymer, of a C 3 -C 8 α,β ethylenically unsaturated monocarboxylic acid at least 35% of acid moieties neutralized with metal ions and said second polymer layer contains pigments, dyes, flakes, flake pigments, or any mixtures thereof; and optionally, a third polymer layer in direct contact with the second layer and adhered to the second polymer layer, wherein the sheet has a distinctness of image of at least 60.
