Provided herein are aqueous dispersions. The aqueous dispersions can comprise a first copolymer derived from one or more ethylenically unsaturated monomers, and a second carboxy-functional copolymer derived from one or more carboxylic acid-containing monomers. The aqueous dispersions can be used to prepare low- or zero-VOC aqueous coating compositions that possess desirable properties, including good block resistance and scrub resistance. Coatings and coating formulations comprising the aqueous dispersion, as well as methods of making and using the same are also provided.
