Abstract:
1. A metallic conductive ink for ink-jet printing, comprising a metal precursor material and a thermally decomposable polymer dissolved in an organic solvent, characterized in that a polymer having a decomposition temperature T c <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 selected from the group consisting of polyphthalaldehyde, polyglutaraldehyde, poly-succinaldehyde, or a polymeric glyoxylic acid, or a glyoxylic acid derivative, and monomeric depolymerization products of the thermally decomposable polymer are used as reductants for the metal precursor material.
