  • Patent number: 5332767
    Abstract: A synthetic resin-coated metal pigment such as aluminum pigment has a silne coating covalently bonded to the surface of the pigment particles, and a three-dimensionally cross-linked synthetic resin coating covalently bonded to the siloxane coating. Production of the coated pigment comprises production of a silicon-organic coating on the pigment surface and then conversion of that coating into a siloxane coating by hydrolysis and condensation, followed by reaction with a low-molecular compound for forming the cross-linked synthetic resin coating. A range of uses of the coated pigment is also set forth.
