Abstract

See full text

An anisotropic electrically conductive film formed by a thermosetting acrylic resin composition is disclosed. The composition contains at least a thermosetting agent (A), a thermo-settable ingredient (B), an acrylic rubber containing hydroxyl groups (C), organic fine particles (D) and electrically conductive particles (E). The thermo-settable ingredient (B) may include a phosphorus-containing acrylic ester (b1). The weight averaged molecular weight of the acrylic rubber containing the hydroxyl groups (C) is not less than 1000000. The organic fine particles (D) include polybutadiene-based fine particles (d1).
