PROCESS FOR PREPARING A MICRO CAPSULE

A process for preparing microcapsules which comprises; dissolving a film-forming polymer in an organic solvent to form a solution, said solvent having a dielectric constant between 10 and 40 and a poor compatibility with liquid paraffins and silicone oils; dispersing a core substance in the solution...

Zusammenfassung:	A process for preparing microcapsules which comprises; dissolving a film-forming polymer in an organic solvent to form a solution, said solvent having a dielectric constant between 10 and 40 and a poor compatibility with liquid paraffins and silicone oils; dispersing a core substance in the solution, to form a first dispersion; dispersing said first dispersion in an encapsulating medium comprising a liquid paraffin or a silicone oil in the form of fine droplets; and evaporating the solvent and the encapsulating medium from the dispersion.
