Abstract
A process for the production of microcapsules comprising bonding chemically or physically a heterocyclic diamine, which is soluble or dispersible in water, to an organic compound in a polar solvent to thereby form a substance, which is insoluble in the polar solvent, and then depositing the substance directly on the surface of particles or droplets of a hydrophobic core material.
