A one-pack type epoxy resin composition which can reconcile high curability with storage stability; a latent hardener for obtaining the composition; and an anisotropically conductive material, conductive adhesive material, insulating adhesive material, sealing material, and the like which are high in storage stability, solvent resistance, and moisture resistance and attain high connection reliability, adhesion strength, and high sealing properties even when cured at a low temperature or in a short time. The latent hardener for epoxy resins comprises an epoxy-resin hardener (A) coated with a coating film (c1) obtained by the reaction of an isocyanate ingredient (b1) 1-95 mass%, excluding 95 mass%, of which is accounted for by a low-molecular bifunctional aliphatic isocyanate compound with an active-hydrogen compound (b2). The one-pack type epoxy resin composition contains the latent hardener. |
