摘要:
Flaky particles of the present invention have a particle size distribution in which a value of D90/D10 is at least 2.0 but not more than 3.0, a value of D10 is at least 4.7 μm but not more than 25 μm, and a maximum particle diameter is 90 μm or less, where D10 is defined as a particle diameter at which a cumulative volume of particles reaches 10% when counted from the smaller side, and D90 is defined as a particle diameter at which a cumulative volume of particles reaches 90% when counted from the smaller side. A luster pigment of the present invention contains flaky particles and at least one selected from a metallic layer and a metallic oxide layer that are formed on at least a part of the surface of each of the flaky particles. The luster pigment has a particle size distribution in which a value of D90/D10 is at least 2.0 but not more than 3.0, a value of D10 is at least 4.7 μm but not more than 25 μm, and a maximum particle diameter is 90 μm or less, where D10 is defined as a particle diameter at which a cumulative volume of particles reaches 10% when counted from the smaller side, and D90 is defined as a particle diameter at which a cumulative volume of particles reaches 90% when counted from the smaller side.
