Claim 0:
1. An aqueous slurry composition, comprising an aqueous medium having dispersed therein oily medium-containing microcapsules, wherein the oily medium-containing microcapsules comprise an ionic acrylate copolymer shell encapsulating said oily medium, wherein said ionic acrylate copolymer is made from only water-soluble monomers, said microcapsules release the oily medium upon removal of the aqueous medium without need for pressure to rupture the microcapsules,
wherein said ionic acrylate copolymer comprises a mono-functional acrylate monomer having an ionic group and a multi-functional acrylate monomer, and
wherein the mono-functional acrylate monomer comprises an ester moiety, the ester moiety comprises 1 to 6 carbon atoms, the ionic group comprises an ionic substituent on one of the carbon atoms of the ester moiety, and the ionic group is a carboxylic, a sulfonic, or an ammonium group.
