ABSTRACT PROCESS FOR THE PRODUCTION OF MICROCAPSULES In a process for the production of microcapsules containing a liquid fill-material, a dispersion- stabilising species is produced in an aqueous acidic medium by interaction of a melamine formaldehyde precondensate and a water soluble polymer, neither of which alone is dispersion stabilising with respect to the liquid fill material, and the precondensate is condensed by acid catalysis to produce a condensate which separates from solution and enwraps the liquid fill material to produce microcapsules,
