Abstract
Polymer fine particles having a number average particle diameter of 50 to 450 nm and a CV value of particle diameter on a number basis of 5% or less, or polymer fine particles having a structural color development property when arranged. An acid value of the polymer fine particles is 5 to 38 mg KOH/g. An emulsion in which the polymer fine particles are dispersed in a medium mainly containing water. In addition, a structure in which the polymer fine particles are arranged and develop color.
