Method of producing photosensitive microcapsules

摘要

A method of producing a photosensitive microcapsule which contains a polymerizable monomer and a polymerization initiator. Soluble water is displaced in the polymerizable monomer by performing one or both of distilling the polymerizable monomer and adding a dehydrating agent to the polymerizable monomer. The polymerization initiator and a first microcapsule-forming material are added to the water-displaced polymerizable monomer to produce a solution. Soluble oxygen in the polymerizable monomer is displaced by performing one or both of bubbling an inert gas and adding an oxygen absorbent to the polymerizable monomer. Soluble oxygen may also be displaced in an ionic surfactant by performing the bubbling and adding of oxygen absorbent. The ionic absorbent is added to the solution containing the polymerizable monomer and polymerization initiator, and then the solution is emulsified. A microcapsule membrane is produced by adding a second microcapsule-forming material to the emulsion.
