Abstract
A process to produce an acid-treated aqueous dispersion is provided. The process comprises contacting a polymer, a water dispersible polyester, water, and at least one acid-generating compound; wherein said polymer comprises repeating units from at least one fluoroalkyl monomer and optionally, at least one ethylenically unsaturated monomer; wherein the acid-generating compound is at least one acid or acid salt.
