ABSTRACT:
A flaky pigment excellent in leafing properties and in adhesion between pigment particles and a coating (resin) was obtained by coating the surface of a flaky pigment with a coupling agent and a phosphate having a perfluoroalkly group or a silane compound. Accordingly, the flaky pigment is excellent as a pigment for coating or printing ink of which brightness and durability are required.
