Abstract:
1. A press-bonding anisotropic conductive resin composition comprising (A) 100 parts by weight of an organopolysiloxane having on the average at least two alkenyl groups per molecule, (B) 0.1 to 10 parts by weight of an adhesion promoter in the form of a resinous copolymer composed mainly of R (C) 0 to 100 parts by weight of finely divided silica, (D) 0.1 to 10 parts by weight of metallized conductive particles comprised of core particles which are plated with one or more metals, the conductive particles having an average particle size of 1 to 50 μm and a true specific gravity of 1 to 5, and (E) an addition reaction curing agent consisting of an organohydrogenpolysiloxane in such amount that 50 to 500 mol % of silicon-bonded hydrogen atoms are available relative to alkenyl groups in the organopolysiloxane (A) and a platinum group catalyst in an amount of 1 to 2,000 ppm of platinum atoms based on the weight of the organopolysiloxane (A), said composition becoming an anisotropic conductor by press bonding.
