CURED EPOXY RESIN MICROPARTICLE, DISPERSION LIQUID THEREOF, AND METHODS FOR PRODUCING THESE

摘要

PROBLEM TO BE SOLVED: To provide a cured epoxy resin microparticle excellent in light resistance and heat resistance; and to provide a dispersion liquid thereof, and industrially advantageous methods for producing these.

SOLUTION: The cured epoxy resin microparticle is obtained by curing an alicyclic epoxy resin (A) with an alicyclic amine-based curing agent (B), and has a glass transition temperature Tg of ≥60°C. The microparticle is produced by adding an alicyclic amine-based curing agent (B) to an emulsion in which an alicyclic epoxy resin (A) is dispersed in a liquid state, and separating a cured epoxy resin microparticle from a cured epoxy resin microparticle dispersion liquid obtained by curing (A) into particles.
