Film comprising mixed solvent barrier and primer layer

Described herein are conformable, stretchable, printable films. In particular, films are described comprising a film substrate, a pressure sensitive adhesive, and a mixed solvent barrier/primer layer comprising a blend of two copolyamides, which are immiscible. This mixed solvent barrier and primer layer can effectively act as both a solvent barrier and a primer layer. 本发明描述了能够适形、能够拉伸、能够打印的膜。特别地，描述了包括膜基底、压敏粘合剂和混合溶剂屏障/底漆层的膜，该混合溶剂屏障/底漆层包含两种共聚酰胺的共混物，所述两种共聚酰胺不能混溶。这种混合溶剂屏障和底漆层能够有效地作为溶剂屏障和底漆层两者。
