Abstract:
1. A method of making a multilayer article, the method comprising: providing a first forming web and a base layer releasably adhered to the first forming web, the base layer comprising a first polymeric material, and the base layer having a first major surface and a second major surface opposite its first major surface; contacting a curable composition with the base layer and a second forming web to form a rolling bank of the curable composition disposed between the base layer and the second forming web, the curable composition comprising a curable polymeric material precursor; passing at least a portion of each of the first forming web, the base layer, the second forming web, and the curable composition through a nip to provide a curable layer precursor while said at least a portion of the curable composition is sandwiched between the base layer and the second forming web; at least partially curing the curable layer precursor to provide a transparent protective layer comprising a second polymeric material, at least one of the first polymeric material and the second polymeric material comprising a polyurethane, the polyurethane having hard segments in an amount of from 35 to 65 percent by weight; separating the first forming web from the base layer; disposing a first adhesive layer on the first major surface of base layer; providing a thermoformable substrate having a first major surface and a second major surface opposite its first major surface; and permanently adhering the first adhesive layer to the second major surface of the thermoformable substrate.
