Patent ID: 8679629

Claim:
A microcapsule comprising: a core containing a hydrophobic liquid or wax within a polymeric shell, wherein solid particles insoluble in the hydrophobic liquid or wax are distributed throughout the core, wherein an oil soluble dispersant polymer is adhered to the surface of the solid insoluble particles, wherein the core comprises: 65 to 99% by weight hydrophobic liquid or wax, 0.95 to 25% by weight solid insoluble particles, 0.05 to 10% by weight oil soluble dispersant polymer based on the weight of the core and in which the components total 100%, and wherein the polymeric shell is formed from: 1 to 95% by weight hydrophobic mono functional ethylenically unsaturated monomer, 5 to 99% by weight polyfunctional ethylenically unsaturated monomer, 0 to 60% by weight other mono functional monomer, based on the weight of the polymeric shell in which all of the components total 100%.
