Abstract
A process for forming certain aqueous polymeric dispersions including a first emulsion polymer having an average particle diameter of 150 to 3000 nanometers and a second emulsion polymer having an average particle diameter of 40 to 600 nanometers where at least the first emulsion polymer particles, when dry, contain at least one void is provided. Also provided are the aqueous polymeric dispersions made by the process and paper or paperboard coatings and paints including the aqueous polymeric dispersions.
