Abstract
Conformable, stretchable, printable films are described. In particular, films that include a film substrate, a pressure sensitive adhesive, and a hybrid solvent barrier/primer layer including a blend of two copolyamides that are not miscible are described. Such hybrid solvent barrier and primer layers may be effective as both a solvent barrier and a primer layer.
