PHOTOLUMINESCENT PIGMENT; COSMETIC, PAINT COMPOSITION, AND RESIN COMPOSITION CONTAINING SAME; AND PHOTOLUMINESCENT PIGMENT PRODUCTION METHOD

摘要

A bright pigment of the present invention is a bright pigment including flaky particles and a metal oxide layer covering each surface of the flaky particles. The metal oxide layer has a thickness variation coefficient (standard deviation of thickness of the metal oxide layer / average thickness of the metal oxide layer) of 20% or less. The bright pigment preferably contains a sodium component, and the sodium component is Na 2 O. The content of Na 2 O in the flaky particles is 3% by mass or more and less than 9.5% by mass. The bright pigment preferably has a specific surface area of 5.0 m 2 /g or less.
