Abstract
The present invention relates to a process for producing microcapsules each including a core-shell type structure having a core portion containing at least one functional compound and a shell portion, the process including: step (1): mixing at least one functional compound, a water-soluble monomer (monomer (A)), a crosslinkable monomer having two or more (meth)acryloyl groups (monomer (B)), an oil-soluble polymerization initiator, an organic chain-transfer agent, and water, to obtain a monomer emulsion; and step (2): heating the monomer emulsion obtained in the step (1) to polymerize the monomers, thereby obtaining microcapsules, the organic chain transfer agent having a ClogP value of 3 or less.
