Title:
POLYMER FINE PARTICLES HAVING STRUCTURAL COLORATION PROPERTIES
Document Type and Number:
WIPO Patent Application WO/2021/193675
Kind Code:
A1
Abstract:
Provided are: polymer fine particles having a number-basis average particle diameter of 50 to 450 nm and a number-basis particle diameter CV of 5% or less; or polymer fine particles that have structural coloration properties when in an ordered arrangement. The acid value of the polymer fine particles is 5 to 38 mgKOH/g. Also provided is an emulsion in which polymer fine particles are dispersed in a medium that is primarily water. Also provided is a structure in which polymer fine particles are in an ordered arrangement and generate a color.
