Abstract
In a conventional self-healing material, although the resin properties after self-healing are restored to the same level as the initial refractoriness and strength of the resin, no further extension of life can be expected. A resin cured product according to the present invention includes: a first vinyl monomer having an ester bond; a second vinyl monomer having a hydroxyl group; a transesterification reaction catalyst; and a boron compound.
