CONDUCTIVE INK COMPOSITION FOR INK-JET PRINTING AND THE METHOD TO INCREASE ADHESIVE STRENGTH BETWEEN METAL PATTERN AND POLYIMIDE SUBSTRATE

摘要

A conductive ink composition for ink-jet printing is provided to improve adhesive strength between a substrate and a metal pattern by adding polymer-based additives and to form metal patterns having excellent conductivity by using an ink-jet printing method quickly. A conductive ink composition for ink-jet printing is obtained by adding polymer-based additives with low resistivity in low temperature heat treatment to the conductive ink for the ink-jet printing comprising metal nanoparticles, water-base and alcohol-based solvent and dispersing agent, to improve the adhesive force with a substrate. The additives are any one selected from a group consisting of 1-vinylimidazole, vivylethoxysilane, 4-vinylpyridine, 2-vinylpiridine, JONCRYL 62, JONCRYL 95, JONCRYL 52, JONCRYL 73, and JONCRYL 58.
