  • Coated particles and production method therefor
    Patent number: 11407863
    Abstract: A coated particle according to the present invention is a coated particle containing a conductive metal-coated particle having a metal film formed on a surface of a core material, the conductive metal-coated particle coated with an insulation layer containing a polymer, wherein the insulation layer has a phosphonium group. The insulation layer preferably contains an insulating fine particle and the fine particle has a phosphonium group on a surface thereof, or the insulation layer is preferably a film having a phosphonium group. In addition, the metal is preferably at least one selected from nickel, gold, nickel alloys, and gold alloys. The polymer constituting the insulation layer is preferably at least one polymerized product selected from styrenes, esters, and nitriles.
