Zusammenfassung:	Various embodiments disclosed relate to a surfacing film. The surfacing film includes a base layer. The base layer includes a thermoplastic polyurethane film comprising a reaction product of a reaction mixture of a diisocyanate, a polyester polyol having a melting temperature of at least about 30 ºC; and a diol chain extender. There are many reasons to use the surfacing film including easier and more cost effective manufacturing of the surfacing film by directly extruding the base layer by mixing the reaction mixture in an extruder. Another reason to use the surfacing film is that the film has improved resistance to discoloration. Another reason to use the film is that the film shows good toughness. Divers modes de réalisation de la présente invention concernent un film de surface. Le film de surface comprend une couche de base. La couche de base comprend un film en polyuréthane thermoplastique comprenant un produit réactionnel d'un mélange réactionnel d'un diisocyanate, d'un polyester polyol ayant une température de fusion d'au moins environ 30 °C ; et d'un allongeur de chaîne diol. Il existe de nombreuses raisons pour utiliser le film de surface notamment une fabrication plus facile et plus économique du film de surface par extrusion directe de la couche de base en mélangeant le mélange réactionnel dans une extrudeuse. Une autre raison pour utiliser le film de surface est que le film présente une résistance améliorée à la décoloration. Une autre raison pour utiliser le film est que le film présente une bonne ténacité.
