ABSTRACT:
Microcapsules containing a hydrophobic liquid are prepared by emulsifying the hydrophobic liquid in a hydrophilic liquid immiscible therewith, polymerizing at least one capsule wall-forming substance present in the continuous phase, and depositing the resulting polymer around the droplets of the hydrophobic liquid thereby to envelop the hydrophobic liquid droplets from outside, wherein prior to the step of emulsifying the hydrophobic liquid, a deposition promotor is caused to be present in the droplets of the hydrophobic liquid so as to promote the deposition of the polymer.
