Title:
ELECTRICAL CONNECTION MATERIAL
Document Type and Number:
WIPO Patent Application WO/2015/056512
Kind Code:
A1
Abstract:
This electrical connection material for an anisotropically-conductive film or the like minimizes the occurrence of warp in the electrical connection parts such as anisotropically-conductive connection parts, and moreover does not diminish the conduction reliability of a connected body obtained by electrical connections such as anisotropically-conductive connections, and has a structure in which a conductive particle-containing layer is sandwiched by a first insulating, thermally curable resin composition layer, and a second insulating, thermally curable resin composition layer. The conductive particle-containing layer is a B-stage resin obtained through photoradical polymerization, by irradiation with light, of a conductive particle-containing resin composition layer containing an acrylate-based radical polymerizable compound, a photoradical polymerization initiator, an epoxy-based, non-radical polymerizable compound, and conductive particles. The first insulating, thermally curable resin composition layer and the second insulating, thermally curable resin composition layer each contain an epoxy-based, non-radical polymerizable compound, and a thermal cationic polymerization initiator or a thermal anionic polymerization initiator.
