The application describes a microcapsule comprising: (i) a lipophilic core material, and (ii) a microcapsule shell, wherein the microcapsule shell is formed by the oil-in-water emulsion polymerization of a monomer mixture, the monomer The mixture consists essentially of (a) greater than 70% to about 99% by weight of at least one multifunctional ethylenically unsaturated monomer, (b) from about 1% to about 30% by weight of at least an unsaturated carboxylic acid monomer or ester thereof, and (c) from about 0% to about 30% by weight of at least one vinyl monomer. Also provided are methods of making the microcapsules and methods of using the microcapsules in various applications. |
