<p>PROBLEM TO BE SOLVED: To provide a microcapsule having a core-shell structure, excellent in shear durability, capable of showing excellent storage stability, heat stability and quick curability when being blended into a curable resin composition.SOLUTION: In a microcapsule having a core-shell structure, a hardening agent for an epoxy resin whose solubility into water is 5 wt% or higher and/or a hardening accelerator are coated with a polymer, and the polymer contains a polymer as much as 50 wt% or more having a hydrogen-bondable polar functional group, and a fracture load thereof is 1 mN or heavier.</p> |
