Anisotropically conductive adhesive composition and anisotropically conductive adhesive film formed from it

摘要

To provide an anisotropically conductive adhesive composition that can be rapidly cured at a low temperature during thermocompression bonding and has a sufficiently long working life, while also exhibiting excellent mutual connection stability after connection between substrates. The anisotropically conductive adhesive composition comprises an epoxy resin comprising a cycloaliphatic epoxy resin and a glycidyl group-containing epoxy resin, an ultraviolet activatable cationic polymerization catalyst and a cationic polymerization retarder, and conductive particles.
