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. ## Claims ### Claim 1 A gold resinate solution for inkjet printing usable to provide an inorganic substrate with a gold decoration by inkjet printing, the gold resinate solution comprising: gold resin balsam sulfide; and a solvent dissolving the gold resin balsam sulfide, wherein 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. ### Claim 2 (depends on 1) The gold resinate solution according to claim 1, wherein the gold resinate solution contains the gold element in a range of 5% by weight to 20% by weight. ### Claim 3 (depends on 2) The gold resinate solution according to claim 2, wherein the gold resinate solution has a viscosity of 25 mPa·s or lower. ### Claim 4 (depends on 2) The gold resinate solution according to claim 2, wherein the solvent contains at least one selected from the group consisting of N-methyl-2-pyrrolidone, benzyl alcohol and benzaldehyde. ### Claim 5 (depends on 2) A method for producing a printed item, the method comprising the steps of: preparing an inorganic substrate; ejecting the gold resinate solution according to claim 2 through an ejection opening of an inkjet device and attaching the gold resinate solution onto a surface of the inorganic substrate; and firing the inorganic substrate having the gold resinate solution attached thereto. ### Claim 6 (depends on 1) The gold resinate solution according to claim 1, wherein the gold resinate solution has a viscosity of 25 mPa·s or lower. ### Claim 7 (depends on 6) The gold resinate solution according to claim 6, wherein the solvent contains at least one selected from the group consisting of N-methyl-2-pyrrolidone, benzyl alcohol and benzaldehyde. ### Claim 8 (depends on 6) A method for producing a printed item, the method comprising the steps of: preparing an inorganic substrate; ejecting the gold resinate solution according to claim 6 through an ejection opening of an inkjet device and attaching the gold resinate solution onto a surface of the inorganic substrate; and firing the inorganic substrate having the gold resinate solution attached thereto. ### Claim 9 (depends on 1) The gold resinate solution according to claim 1, wherein the solvent contains at least one selected from the group consisting of N-methyl-2-pyrrolidone, benzyl alcohol and benzaldehyde. ### Claim 10 (depends on 9) A method for producing a printed item, the method comprising the steps of: preparing an inorganic substrate; ejecting the gold resinate solution according to claim 9 through an ejection opening of an inkjet device and attaching the gold resinate solution onto a surface of the inorganic substrate; and firing the inorganic substrate having the gold resinate solution attached thereto. ### Claim 11 (depends on 1) A method for producing a printed item, the method comprising the steps of: preparing an inorganic substrate; ejecting the gold resinate solution according to claim 1 through an ejection opening of an inkjet device and attaching the gold resinate solution onto a surface of the inorganic substrate; and firing the inorganic substrate having the gold resinate solution attached thereto.
