Claim 0:
1. A method of producing a conductive copper coating on a substrate, the method comprising: coating a substrate with a copper-based ink comprising copper acetate, 3-dimethylamino-1,2-propanediol and a silver salt, wherein the copper acetate and 3-dimethylamino-1,2-propanediol are in a molar ratio of about 1:1 to about 1:2; and, decomposing the ink on the substrate to form a conductive copper coating on the substrate, wherein the decomposing comprises thermal sintering in the presence of oxygen in an amount of 100 ppm to about 500 ppm of oxygen or photo-sintering in air, wherein the ink further comprises a solvent and a binder, the binder comprising a hydroxyl- and/or carboxyl-terminated polyester.
