Title: COATED PIGMENT
Abstract:
The purpose of the present invention is to provide a coated pigment that is constituted by composite particles obtained by coating the surfaces of metal particles with a silicon compound, and that can be dispersed in a state with comparatively few aggregates. The present invention pertains to a coated pigment constituted by composite particles comprising metal particles and one or more coating layers on the surfaces thereof, the pigment being characterized in that (1) at least one of the coating layers is a silicon-compound-containing layer, and (2) the proportion of aggregates constituted by at least four of the composite particles is 35% or less.
