Abstract:
A peelable coating composition, comprising:a. an aqueous dispersion of at least one polymer, wherein said polymer has a Tg of greater than 0Â° C. to 40Â° C.; b. at least one amphoteric release agent having an isoelectric point at pH 3 to pH 8; c. greater than 0.20 moles/100 grams of said polymer to 2.00 moles/100 grams of said polymer of at least one base capable of maintaining said coating composition from pH 8 to pH 11; and d. optionally, at least one polyvalent metal cation; wherein the sum of the amounts of said base and said polyvalent metal cation is greater than 0.20 moles/100 grams of said polymer to 2.00 moles/100 grams of said polymer.
