Title:
MICROCAPSULE PRODUCTION METHOD AND MICROCAPSULE
Document Type and Number:
WIPO Patent Application WO/2014/109412
Kind Code:
A1
Abstract:
In this microcapsule, which comprises a core material that is a functional organic compound and a shell material that is a cross-linked or non-cross-linked polymer compound, efficiency and stabilization of expression of the function of the core material is achieved. This microcapsule is achieved by use of a microcapsule production method which has as the raw material an O/W dispersion containing an organic compound that does not contain a vinyl group and containing at least one type of vinyl monomer, and which involves a polymerization reaction of the vinyl monomer compound to produce a microcapsule having a core-shell structure in which the core is an organic compound not containing a vinyl group and the shell is a polymer of the vinyl monomer compound; this method is characterized by involving a step in which, before the polymerization reaction, the O/W dispersion undergoes emulsification treatment by being made to pass continuously and sequentially through multiple mesh-like bodies arranged maintaining a fixed interval along the flow path.
