Inline coated polyester film with thermally stable and releasable coating

摘要

A biaxially oriented polyester film with a substantially non-crosslinked polymeric coating consisting essentially of a styrene/acrylate copolymer emulsion, wherein the coating is highly thermally stable with a primary onset temperature of greater than about 350° C., having a glass transition temperature between about 0° C. and about 50° C., having a rapid solubility in a low molecular weight organic solvent, and having a surface energy of greater than about 35 dyne/cm and less than about 40 dyne/cm.
