ANISOTROPIC CONDUCTIVE FILM COMPOSITION FOR HIGH RELIABILITY AND ADHEISION

摘要

A composition for an anisotropic conductive film, and an anisotropic conductive film prepared from the composition are provided to improve initial adhesive strength, to reduce contact resistance and to enhance reliance even under the condition of high temperature and high humidity. A composition for an anisotropic conductive film comprises 5-50 wt% of at least one kind of resin selected from polyurethane and its modified resin; 5-50 wt% of at least one kind of resin selected from an indene resin and its copolymer; 1-50 wt% of a (meth)acrylate oligomer or polymer; 1-30 wt% of a (meth)acrylate monomer; 0.1-15 wt% of a radical initiator; and 0.01-20 wt% of a conductive particle. Preferably the polyurethane and its modified resin have an average molecular weight (Mw) of about 10,000-1,000,000.
