METALLICALLY CONDUCTIVE INK FOR INK-JET PRINTING AND METHOD FOR PRODUCING THE SAME

摘要

The invention relates to a metallic, conductive ink for ink-jet printing, comprising a metal precursor material, in particular an organometallic decomposition compound, and a thermally decomposable polymer dissolved in an organic solvent, wherein a polymer having a decomposition temperature Tc < 150°C is contained as the thermally decomposable polymer, the polymer is selected from a cyclic polyacetal having blocked terminal groups, a cyclic polyaldehyde comprising bifunctional monomers, such as polyphthalaldehyde, polyglutaraldehyde, polysuccinaldehyde, and a polymeric glyoxylic acid, or a glyoxylic acid derivative, such as poly(methyl glyoxylate), and monomeric depolymerization products of the thermally decomposable polymer are used as reductants for the metal precursor material. The invention further relates to a method for producing the ink.
