Abstract
To produce a conductive epoxy resin composition with improvement in the characteristics of rapid-curability, heat resistance and moisture resistance, adhesion reliability, storage properties and low-temperature curability that can be used effectively for production of conductive adhesive films. The conductive epoxy resin composition comprises an alicyclic epoxy resin, optional diols, a styrenic thermoplastic elastomer with an epoxy group in the molecule, an ultraviolet activated cationic polymerization catalyst, an optional tackifier having an aromatic ring in the molecule, and conductive particles.
