Beschreibung
Zusammenfassung:	Described herein is a multilayered paint film, which comprises in order: (i) a hard coat layer comprising a thermoplastic polyurethane having a hard segment content of 80 percent by weight or greater, wherein the thermoplastic polyurethane is a reaction product of: (a) a diisocyanate; (b) a polyol optionally comprising a cyclic structure; and (c) a chain extender, wherein at least one of the polyol or the chain extender comprises at least one side chain and at least one of the diisocyanate or the chain extender comprises a cyclic structure; (ii) a colored polymeric resin layer comprising a colorant, wherein the colored polymeric resin layer is 50-250 micrometers thick; and (c) an adhesive layer, wherein the adhesive layer comprises a pressure sensitive adhesive or a hotmelt adhesive. In one embodiment, the multilayered paint films may be used to cover parts for automotive and aerospace applications.
