Abstract:
1. A microcapsule-based hardener for an epoxy resin comprising: a core (C) formed using a hardener (H) for the epoxy resin as a starting material and; a shell (S) covering the core (C) therewith, wherein: the hardener (H) for the epoxy resin has an amine adduct (A) as a main component and the amine adduct (A) is available by a reaction between an epoxy resin (e1) and an amine compound; the hardener (H) for the epoxy resin has an average particle size exceeding 0.3 μm and not greater than 12 μm and contains 0.1 to 15% of small-particle-size hardener components, which are components having a particle size 0.5 times or less of the average particle size of the hardener (H) for the epoxy resin; and the shell (S) has, at least on the surface thereof, a binding group (x) capable of absorbing an infrared ray having a wave number of from 1630 to 1680 cm
