Abstract: Described herein is a multilayered article and methods of making and using such articles. The multilayered article comprises: · (a) a microsphere layer comprising a plurality of microspheres (11) disposed in a monolayer; · (b) a bead bonding layer (12) comprising a first major surface and a second opposing major surface wherein the plurality of microspheres is at least partially embedded in the first major surface of the bead bonding layer, and wherein the bead bonding layer comprises a thermoset polyurethane, and wherein the thermoset polyurethane is derived from one or more liquid polyols; and · (c) an elastomeric layer (14) disposed on the second opposing major surface of the bead bonding layer.

Abstract: 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° C.; 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.
