ABSTRACT:
The present invention provides aqueous dispersions that, for example, include the reaction product of an oxirane-functional vinyl addition polymer having an oxirane functionality between 0.5 and 5; an acid-functional polymer having an acid number 30 to 500; and a tertiary amine. Also described are coating compositions containing the dispersion and methods of forming the dispersion.
