Resumen de: EP3689984A1

A flake-less molecular ink suitable for printing (e.g. screen printing) conductive traces on a substrate has 5-75 wt% of bis(2-ethyl-1-hexylamine) copper (II) formate, bis(octylamine) copper (II) formate or tris(octylamine) copper (II) formate, 0.25-10 wt% of a polymeric binder and balance of at least one organic solvent, all weights based on total weight of the composition. Conductive traces formed with the molecular ink are thinner, have lower resistivity, have greater adhesion to a substrate than metal flake inks, have better print resolution and are up to 8 times less rough than metal flake inks. In addition, the shear force required to remove light emitting diodes bonded to the traces using Loctite 3880 is at least 1.3 times stronger than for commercially available flake-based inks.
