Abstract: A paint replacement film comprising a polymer layer comprising a polyurethane produced from a formulation comprising at least one blocked isocyanate. The paint replacement film comprises a liner layer and the formulation comprises at least two polyols in OH weight equivalent ratio in the range 4.5:1 to 1:4.5. The formulation may comprise a colourant and the polyurethane may have a glass transition temperature (Tg) below 42° C. Also disclosed is a method of producing a paint replacement film, by providing a backing layer, providing the liquid formulation, cast-coating the backing layer with the liquid formulation, and gelling the liquid formulation, thereby forming a polymer layer comprising polyurethane. The paint replacement films are useful for replacing paint on surfaces especially in automotive applications.

Abstract translation: 一种涂料更换膜，其包含聚合物层，所述聚合物层包含由包含至少一种封端异氰酸酯的制剂制备的聚氨 涂料更换膜包括衬里层，并且制剂包含OH重量当量比为4.5:1至1:4.5的至少两种多元醇。 制剂可以包含着色剂，并且聚氨酯可以具有低于42℃的玻璃化转变温度（Tg）。还公开了制备涂料更换膜的方法，通过提供背衬层，提供液体制剂，浇铸涂层 背衬层和液体制剂，并使液体制剂胶凝，从而形成包含聚氨酯的聚合物层。 涂料更换膜可用于更换表面上的油漆，特别是在汽车应用中。
