Abstract

The present application is directed to a non-aqueous composition. The composition comprises a blend of an acidic copolymer derived from a first group of monomers comprising at least one acidic monomer, and a basic copolymer derived from a second group of monomers comprising at least one basic monomer. The basic copolymer may comprise an amide functionality. In some embodiments, the composition comprises an acidic (meth)acrylic copolymer having a Tg less than 0° C., which is derived from a first group of monomers comprising at least one acidic monomer, and a basic (meth)acrylic copolymer having a Tg less than 0° C., which is derived from a second group of monomers comprising at least one basic monomer. Additionally, the composition may comprise a minimum of 0.10 moles of acid/base pairs per kilogram of composition.
