Conductive ink

Abstract

The invention relates to an ink composition for printing conductive tracks with high electrical conductivity for electronic applications, and which can be recycled to recover the conductive particles via an environmentally friendly extraction process for re-use, without further processing, in a further conductive ink composition. Also provided are substrates comprising a printed current track formed from such compositions; substrates comprising a surface mount electronic component adhered to said substrate via contact with an adhesive composition formed from such ink compositions; and substrates comprising a conductive coating formed from such ink compositions for use in, e.g., induction sealing and/or to provide an antimicrobial coating. Methods of forming such printed tracks, coated substrates and/or adhering surface mount components to a substrate are also provided.
