Abstract: Stretchable, multilayer films are disclosed that include a thermoplastic polyurethane substrate and a thermoset coating, applied to the thermoplastic polyurethane substrate. The thermoset coating may comprise the reaction product of: an oligomeric polyester resin comprising the reaction product of: diols or polyols comprising from about 30 to about 99 mol % trimethylolpropane and from about 1 mol % to about 70 mol % neopentyl glycol, in each case based on the total molar amount of diols and polyols reacted, and dicarboxylic acids or polycarboxylic acids comprising from about 1 mol % to about 70 mol % of one or more cyclic or acyclic aliphatic acids having from 2 to 12 carbons, based on the total molar amount of dicarboxylic acids and polycarboxylic acids reacted.

Abstract: Functional film systems are disclosed that include a functional film having a surface energy; and a cap sheet, adjacent to the functional film, having a surface energy. In aspects, the ratio of the surface energy of the cap sheet to the functional film, measured at a point where the cap sheet contacts the functional film, is no greater than 2.6; and the peel strength may be from about 1 to about 50.
