Beschreibung
Zusammenfassung: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.
