PROCESS FOR PRODUCING FINELY DIVIDED OPAQUE PARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a process for producing colored finely divided opaque particles based on an aminoformaldehyde resin. SOLUTION: A new pigment for making colored finely divided particles based on an aminoaldehyde resin is provided, which makes it possible to produce particles of substantially uniform particle size and spherical or irregular shape, having excellent dispersibility and superior opacity.
