Multi-layered colored surface protection films

Abstract

Multi-layer surface protection films for use as a coating for surfaces on a wide range of applications, such as automobiles, wind turbine blades, appliances, electronic displays, mobile devices, and the like. The surface protection films comprise a first layer comprising a pigment or dye and having first and second opposing surfaces, a second layer comprising thermoplastic polyurethane (TPU) in contact with the first surface of the first layer and an adhesive adjacent the second surface of the first layer. The TPU may be extruded onto the colored first layer to increase the durability of the colored layer while maintaining equivalent or superior performance to conventional colored protective films.
