ABSTRACT:
The present invention describes a process for priming a polymeric film with a primer coating composition and overcoating with a silicone release coating. Silicone release films are well known and serve as temporary supports for an adhesive or tacky surface such as for labels, pressure sensitive tape, etc. The primer coating composition, before dilution with water, comprises from about 25 to 75% by weight of a glycidoxy silane and from about 75 to 25% by weight of a copolyester. The copolyester comprises from about 40 to 98 mol percent isophthalic acid; from about 0 to about 50 mol percent of at least one aliphatic dicarboxylic acid; from about 2 to about 20 mol percent of at least one sulfonate group attached to a dicarboxylic nucleus; and about 100 mol percent of glycol having from about 2 to 11 carbon atoms. Typical glycidoxy silanes that can be employed in the primer coating composition include glycidoxypropyltrimethoxysilane.
