More Information
Summary:A method for producing coated copper particles having a surface coated with an aliphatic carboxylic acid, wherein the method comprises obtaining a reaction mixture containing copper formate, an amino alcohol, an aliphatic carboxylic acid having an aliphatic group having 5 or more carbon atoms, and a solvent, and subjecting a complex compound formed in the reaction mixture to thermal decomposition treatment to form metal copper, wherein a ”SP value, which is a difference in SP value between the amino alcohol and the solvent, is 4.2 or more.
