Composition for anisotropic conductive film with excellent adhesive strength and anisotropic conductive film using same

摘要

A composition for an anisotropic conductive film is provided to realize excellent room temperature stability, stable conductivity even under a short-time compression condition, flowability and adhesion maintenance. A composition for an anisotropic conductive film comprises: (i) an ethylene-vinyl acetate copolymer; (ii) a radical polymerizable material; (iii) at least one radical initiator selected from diacyl peroxide, peroxydicarbonate and peroxyester; (iv) at least one radical initiator selected from peroxyketal and dialkyl peroxide; and (v) conductive particles. In a variant, the composition further comprises a film-forming polymer resin.
