PARTICLES, ANTI-FORGERY INK, ANTI-FORGERY TONER, ANTI-FORGERY SHEET, ANTI-FORGERY MEDIUM, AND METHOD FOR MANUFACTURING PARTICLES

摘要

The primary purpose of the present invention is to provide novel particles for anti-forgery technology using particles. The present invention achieves the above by providing particles characterized by having a three-dimensional shape that is distinguishable under magnified observation and having at least a curved surface in the three-dimensional shape.
