<p>The invention described herein relates to a method of preparing microcapsules comprising a capsule core, a polymeric capsule wall and also, disposed on the outer surface of the capsule wall, a polyelectrolyte having an average molecular weight in the range from 500 g/mol to 10 million g/mol, the polymeric capsule wall being formed from specified monomers, where the microcapsules have an average particle size of 1.5-2.5μm and 90% of the particles have a particle size≰4μm, by microencapsulating a capsule core with a polymeric capsule wall and then contacting the polymeric capsule wall with one or more polyelectrolytes in water or an aqueous medium.</p> |
