Abstract: The present invention relates to an aqueous dispersion comprising dispersed particles of an acrylic copolymer having a volume average particle size diameter (d50) of from 1 to 50 μm (microns), wherein the aqueous dispersion further comprises (i) an acrylic copolymer dispersant having an alkaline solubility higher than 50 wt. %, and being present in the dispersion in an amount of from 10 to 35% by weight, relative to the total amount of monomers used to prepare the acrylic copolymer of the dispersed polymeric particles; and (ii) decomposition products of an oil-soluble organic initiator.
