Patent ID: 11898045

Abstract:
Provided by the present invention is a technology to realize a gold decoration on a surface of an inorganic substrate by inkjet printing. The gold resinate solution for inkjet printing disclosed herein is usable to provide an inorganic substrate with a gold decoration by inkjet printing. The gold resinate solution contains gold resin balsam sulfide; and a solvent dissolving the gold resin balsam sulfide. The gold resin balsam sulfide has a ratio (IAu/IS ratio) of a peak intensity IAu derived from gold element (Au) with respect to a peak intensity IS derived from sulfur element (S), in X-ray fluorescence analysis, of 8.5 or higher. The gold resinate solution having an IAu/IS ratio of 8.5 or higher may have the viscosity thereof kept low even if containing a large amount of gold, and therefore, may realize a gold decoration on an inorganic substrate by inkjet printing.
