Title:
MANUFACTURING METHOD OF MICROCAPSULE
Document Type and Number:
Japanese Patent JP2007083167
Kind Code:
A
Abstract:
To provide a method which enables an easy manufacture of even a microcapsule (1) with a large membrane thickness (t2) in which a synthetic polymer constituting a membrane material (2) is not limited to a copolymer of an oily soluble monomer with a water soluble monomer.
The manufacturing method of the microcapsule comprises the following procedure: Synthetic polymer particles (2) of a hollow structure are dispersed in an organic solvent followed by dissolving an oily core material (1) in the solvent. Water is then added to the resultant organic solvent mixture while removing the organic solvent to allow the synthetic polymer particle (2) contain the core material (3).
