Document Type and Number:
WIPO Patent Application WO/2013/085050
Kind Code:
A1
Abstract:
This photoluminescent pigment is a photoluminescent pigment including flaky particles, and a metal oxide layer coating the surface of the flaky particles. The coefficient of variation (standard deviation for the thickness of the metal oxide layer/average thickness of the metal oxide layer) for the thickness of the metal oxide layer is no more than 20%. Preferably, the photoluminescent pigment includes a sodium component, the sodium component is Na2O, and the Na2O content in the flaky particles is 3%-9.5% by mass. The specific surface area of the photoluminescent pigment is preferably no greater than 5.0 m2/g.
