PROBLEM TO BE SOLVED: To provide a new method for manufacturing a gold resinate suitable for a gold resinate paste capable of forming a gold coating having a sheet resistance even by sintering at a low-temperature of 250°C or less achieved by improving a difficulty in sintering a conventional gold resinate paste at a high temperature.SOLUTION: A gold resinate is obtained in a high yield by adjusting an aqueous solution of a gold compound represented by the general formula (1) to a pH of 7.0-14.0, keeping the solution at a temperature of 0-100°C and adding alkane thiols selected from 1-ethane thiol, 1-propane thiol, 1-butane thiol, 1-pentane thiol and 1-hexane thiol to the solution to react the gold compound with the alkane thiols for 1-15 minutes.SELECTED DRAWING: None |
