A multi-layer sheet and a process for producing the sheet are disclosed. The sheet can comprise a first polymer layer comprising a weatherable film of polyvinyl fluoride (PVF) or polyvinylidene fluoride (PVDF) having an adhesive coating on one side; second pigmented polymer layer extruded onto the adhesive coating of the first polymer layer; and optionally a third extruded thermoformable polymer backing layer. The process can comprise combining a pigmented polymer onto the adhesive coating surface of the weatherable film of PVF or PVDF, passing the resulting structure into a nip of two rolls under pressure and subsequently an optional third thermoformable polymer backing layer is extruded or laminated onto the pigmented polymer layer.
