Bright pigment, method for producing the pigment, and waterborne resin composition containing the pigment

摘要

A bright pigment of the present invention includes a scaly inorganic base 10, a silver-containing coating 11 that covers the inorganic base 10 and contains silver or a silver alloy, and a yellowing-suppressing coating 2 that covers the inorganic base 10 from outside of the silver-containing coating 11 and contains a metal compound functioning as an oxidizing agent. The metal compound is preferably at least one selected from the group consisting of a hydroxide of metal, an oxide hydrate of metal, and a salt of an oxide hydrate of metal, and the metal is at least one selected from the group consisting of tungsten, molybdenum, bismuth, vanadium, or cerium.
