Zusammenfassung:	Polyvinyl chloride compositions and films formed therefrom are described which exhibit improved printability and resistance to weathering. The compositions generally comprise polyvinyl chloride having a certain molecular weight, at least one bio-based plasticizer, at least one UV absorber, at least one hindered amine light stabilizer, at least one heat stabilizer, and at least one acid scavenger. Also described are various vinyl-based laminates using the films which can be for example adhesive laminates. Also described are methods of producing the noted films and laminates. L'invention concerne des compositions de polychlorure de vinyle (PVC) et des films formés à partir de ces dernières, qui affichent une imprimabilité et une résistance aux intempéries améliorées. Les compositions comprennent généralement du polychlorure de vinyle présentant une certaine masse moléculaire, au moins un plastifiant à base biologique, au moins un absorbeur UV, au moins un stabilisateur de lumière amine encombrée, au moins un stabilisant thermique et au moins un capteur d'acide. L'invention concerne également divers stratifiés à base de vinyle utilisant les films qui peuvent être, par exemple, des stratifiés adhésifs. L'invention concerne également des procédés de production des films et des stratifiés indiqués.
