Abstract: 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.

Abstract: The present disclosure provides an extrudable article and a composition, each including at least one polyurethane including hydroxyl groups and latent isocyanate groups in the form of uretdione groups. The hydroxyl groups are present on a first polyurethane and the latent isocyanate groups are present on either the first polyurethane or a second polyurethane and a ratio of the latent isocyanate groups to the hydroxyl groups is greater than 1.2 : 1. A method of making the extrudable article is provided including reacting in an extruder a polymerizable composition including a uretdione-containing material including a reaction product of a diisocyanate reacted with itself, a hydroxyl-containing compound, and an isocyanate-containing compound. A method of making a core-sheath filament is provided including forming a core composition of the at least one polyurethane and wrapping a sheath composition including an ethylene copolymer or a polyolefin around the core composition. Further, methods of printing a composition are provided including heating and mixing the extrudable article, such as in an extruder, to form a molten composition, then dispensing the molten composition through a nozzle onto a substrate.
