摘要： A process for the preparation of microcapsules comprising the steps of—preparing an oil-phase comprising a multifunctional ethylenically unsaturated monomer or oligomer wherein the water solubility of the multifunctional ethylenically unsaturated monomer or oligomer at 20° C. in deionised water is less than 2 gram/litre, —forming an oil-in-water emulsion with the oil phase, —subjecting the oil-in-water emulsion to conditions suitable to initiate interfacial polymerization at the oil-water interface using a radical initiator with a water solubility at 20° C. in deionised water which is at least 1 gram/litre.
