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 of a styrene/acrylate copolymer emulsion, wherein the coating is highly thermally stable with a primary onset temperature of greater than about 350 DEG C, having a glass transition temperature between about 0 DEG C and about 50 DEG 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.
