Silicone coated film with back side slip control coating and method of controlling slip of such film |
摘要 |
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 comprises a binder, preferably a water-soluble copolyester comprising about 50 to about 98 mol percent isophthalic acid, about 2 to about 20 mol percent of at least one sulfomonomer containing a sulfonate group attached to a dicarboxylic nucleus, and about 100 mol percent of at least one copolymerizable glycol having from about 2 to about 11 carbon atoms; and also 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.
