Zusammenfassung:A circuit article for use with an inkjet printer pen. The circuit article comprises a flexible circuit having a plurality of conductive traces disposed on a dielectric film, an adhesive film disposed adjacent the dielectric film of the flexible circuit, and a carrier film disposed adjacent the first adhesive film, opposite of the flexible circuit. The adhesive film is derived from a cross-linkable precursor comprising an epoxidized aromatic-diene block copolymer and a thermal-curing agent.
