Abstract: A dispersion includes a hyperbranched polymer having latent crosslinking functionality and comprising the reaction product of: a partially neutralized, acid-functional resin; and an epoxy; and optionally, an effective amount of a crosslinking agent; wherein: the partially neutralized, acid-functional resin comprises the reaction product of a mixture of: a first acid-functional resin with a base and a second acid-functional resin; or a first and a second acid-functional resin with a base; the first acid-functional resin is not the same as the second acid-functional resin; at least one of the acid functional resins comprises a further functional group capable of Schiff-Base crosslinking after film formation; and the dispersion is a single pack waterborne polymer dispersion.
