ABSTRACT:
The present invention relates to an adhesive composition for an electro-magnetic shielding film and an electro-magnetic shielding filter using the same, and more particularly to an adhesive composition for an electromagnetic shielding film comprising: a) an acrylic copolymer of i) (meth)acrylate ester monomers having C1, to C12alkyl groups and ii) vinylic monomers having hydroxyl groups; and b) a multifunctional isocyanate crosslinking agent. The electro-magnetic shielding filter of the present invention offers good durability because transparentization is performed with an acrylic adhesive composition having no acidic groups, and thus oxidation of copper is prevented.
