  • Process for producing resin-coated metal particles, resin-coated metal particles, and toner for forming circuit
    Patent number: 8053073
    Abstract: A process for producing resin-coated metal particles includes coating surfaces of metal particles with silica; allowing a polymerizable group to adsorb onto the surfaces of the silica-coated particles by the use of a silane coupling agent; and coating the surfaces of the silica-coated particles with a polymeric resin by mixing the particles to which the polymerizable groups have been adsorbed, a polymerizable monomer, a polymerization initiator, and a dispersant to polymerize the polymerizable monomer and the polymerizable groups.
    Type: Grant
    Filed: September 15, 2004
    Date of Patent: November 8, 2011
    Assignee: Murata Manufacturing Co., Ltd.
    Inventors: Kiyoko Ueda, Ichiro Nakamura, Kiyoyasu Sakurada
