Title:
METAL PIGMENT, APPLICATION OF METAL PIGMENT, AND METHOD FOR MANUFACTURING METAL PIGMENT
Document Type and Number:
WIPO Patent Application WO/2022/154001
Kind Code:
A1
Abstract:
Provided are a metal pigment containing novel composite particles that have not been seen in conventional technologies and a method for manufacturing a metal pigment having reduced flocculation. The problem is solved by a metal pigment containing metal particles and composite particles having one or more coating layers formed on surfaces of the metal particles, or the like, the metal pigment being characterized in that (1) the composite particles have a scale-like shape, (2) a volume-based diameter D50 is 0.1 to 30 μm when a particle size distribution of the composite particles is measured by a laser diffraction type particle size distribution meter, and (3) the composite particles have an average thickness of 15 to 300 nm.
