Abstract
The present invention relates to a self-supporting polymer film with a silicone-containing coating layer on the front surface that is capable of releasing free silicone oil and a slip control coating on the back surface, where the slip control coating has an exposed surface adapted to contact the free silicone oil. The slip control coating includes water soluble copolyester; and optionally includes a coupler, preferably a silane. A method for controlling the slip of silicone coated film by coating the back side of the film with this slip control coating is also disclosed.
